been using TrackIR for many years now. It's great when racing on one screen. Great piece of kit

I was about to comment about the 50:50 grind, and you already said it. Legend. 😆 Great drive as always!

Lovely driving and the whole video is so relaxing.

Track IR is all about how you set it up. I have used it for many years across many genres of pc gaming starting with flight combat sims and my now love, sim racing. It is essentially plug and play and you can use the standard setup for most things but becoming confident in the use of the profile editor is when Track IR comes alive. I have Track IR 5 with both types of reflectors. The clip is definitely better holding calibration more efficiently than the hat reflectors. The downside is the cable, which is a pita, but that is due to my rig situation. I use the cap reflectors taped to my headset for most of my racing and it's great. As I said earlier though it is all about setup and getting to know what and what you cannot do. In that respect it isn't new user friendly although once you understand how to do it it is so versatile. For instance in my sim rig racing setup I have actually disabled the up and down axis's and have a large dead zone in the middle. This means I have a very stable look ahead when I am racing but just a quick glance to the sides gives me a better view than the left and right views in AAC at least. How much you have to move your own head to perform any of these actions is totally programable. You can set it up so a tiny movement to the left or right will pan behind you (check six in Combat Flight Sims) or have it on a virtually one to one basis, which is great for the realism buffs out there. Great bit of kit and I am surprised more don't speak about Track IR's merits in sim racing. One thing I will say compared to VR is that if you mount the reflectors on your headphone it helps massively with a problem that effects most sim racers in the summer months, heat. VR in my experience has the opposite effect and after taking the headset off after a session sometimes I am basically just a sweaty mess lol.

What a risk for Filip to enter the corner and hope he made the carousel. That cost him the position and it was only half way through. Live to fight another battle but he was impatient. Good stuff. I considered the Track IR but some folks are not keen on it for iRacing. Thanks for the content.

I was using TrackIR for years (now back to VR again) and love it. Certainly less is more and I've set it up so it's linear and slow in the center and accelerate if looking at the edges of the 49" to get full 180° if I want, even a bit more. I've never had the wish to "upgrade" the 49" to a triple-setup because it feels like triples if you can look around and never failed during a race. And the maximum vertical FOV is certainly bigger than any triple-screens available even it's quite limited compare to VR. The cap-reflectors are okay, but the TrackClip Pro is definitely worth it. It's more stable and needs no light source in front of you to reflect light. The downside is, it needs a 2nd cable and not much con for me, because I'm using tethered headphones anyway and fixing the TrackIR-cable to the headset cable is not a big deal. Both solutions don't like direct sunlight or reflections of sunlight from stuff in the room and both can fail if not using it in game for a while without TrackIR-restart, but far less with TrackClip Pro. The Cap-reflectors have the advantage that they don't change position if you leave the rig for some minutes while it's rather unlikely that you put your headphones on exactly the same as before, so last one needs more re-centering. Just don't forget to take off your cap if you go shopping😀

I can remember when you were learning Nordschleif, now it's like a morning commute for you 😂. Great driving, superb defense.

I’ve found time with track IR. I believe it’s more natural to bring the car/plane to where I’m looking than to move the vehicle to where you want to look. I have friends that try the rig and the tracking is too much. Ymmv, but it’s worth a peek.

Top video Dave!

You finally caught up with TrackIR5. Keep settings low, turn off world movement etc in game, and its a blast. If you want the trackclip wireless, the cheap Amazon Wireless LED Clip TrackClip option is easily the best I've used so far. With my G9 Ultra Wide its a perfect combo. That hat clip makes us all look special mate. :-) Good vid. 👍

If you do a dedicated video on Track IR, it would be great if you included your recommended settings.

Great drive Dave

Wow you are so quick with this little menace Dave! I was in your race here btw, #21 car, hello from there :D

Bloody nice drivin Dave

ive had TrackIR for years now, using for several sims, racing, flight, and infantry combat (Arma) and i never regretted buying it for a single moment.

I loved my trackir! I used it on my desk setups. As I packed the space for rigs. Looking to bring it back when I build my rig even tho I have a G9

This is a blast from the past, for me. I used Track IR back before I started using VR. I do agree with Dave in regard to "less is more". I had mine set up to give me small movements to left and right and enough movement to glance down at the dash or steering wheel display. I still keep it around as a backup for when my HP Reverb decides to give up on me. I almost consider it a must for racing on a single screen.

amazing race

As a Head Tracking user I thoroughly enjoyed this! "Please Sir I Want Some More" I wouldn't mind seeing you do this again at Summit Point where there are more tighter corners.

I found the FF1600 on the Nord was a mental car/track combo. Really enjoyable if you can keep it on the black stuff.

Thanks Dave!

Ahh. Memories of this back when I used to play GTR 2 full time in the pre 2010 era. Support for this was built in to the sim, however I had always yearned for a pair of VR glasses, which effectively had this and the screen in one unit.. Eventually got my HTC Vive back in 2016 and never looked back for sim racing. I had assumed VR had put Track-IR on the back footing. Nice to see they are still around.

TrackIR is a great help to me as I only have a 27inch screen, and have to lower the FOV a lot to get the correct setting. TrackIR allows me to view all the cockpit readouts and the mirrors, even though I cant see them when looking forward.

I never used trackir for racing. But I use it alot for ETS2, FS22, elite dangerous and flightsim. It's really immersive.

I used TrackIR in iRacing when I was on a single monitor setup, it really help finding the apexs and looking at cars next to me.

TRackir is a fantastic product, not just in racing/flight sims but in Arma 3 as well.

Find one of the third-party headclips that replace the PRO that NP manufactures. The wirelessness is crucial for the best experience. Just getting into iRacing with your content after spending a fair amount of time doing flight sims; great channel! Amazed how uncommon TrackIR is among sim racers; it's virtually required for flight simming if you're not already running a full VR setup.

It's all about the sense of depth, it's the same in VR but VR has double the effect because you have the depth of movement and the visual depth. But yea it's a game changer IMO 🙌

another good way to set it up is with the head roll axis instead of looking to the sides, then when you into the corners it automatically looks into it.

Great racing. Been using Trackir for a long time. Buying a wireless pro clip was one of my best purchases. 20hour battery life and charges via usb. Saves the wire hanging from your headphones.

This is pretty cool. I'll have to give it a try. I think this would be sweet on a 32:9. I feel like I sometimes leave too much space when racing side by side with drivers on ovals and it hinders my corner exit speed and ability to side-draft.

Did you look up Dario ? Dario Frattini, has the rare achievement of having won an official race in every major road series in iRacing.

Iam racing with trackir it is a lot more intuitive for me with one screen :) I use delan clip as track ir you need to set up curves carefully but yeah it works well :) looking into and out from corners is the best. Immersion is really great with head tracking :)

I use both together - triples plus opentrack plus cheapo webcam. Works beautifully and I think I have yaw locked to a max of 5 degrees. Something very, very small anyway.

I set up head tracking recently using OpenTrack and a $15 webcam. I tuned it so up and down does nothing, and yaw is set to a max which is the tiniest of movements. I only need a few degrees of motion as I have triple screens, but it does feel very natural driving with no special headset on and with the screen reacting ever so slightly to my head movements.

Wow Dario was quick there Dave. Good racing but that was a costly mistake that caused you to lose draft.

Looking forward to seeing your next video on TrackIR. I haven't heard of it before so I am definitely curious. VR on a Quest 2 was incredible in iracing but the graphics quality was terrible and I didn't like the FOV.

I used trackir and it was nice but compared to a good performing VR there is no comparison.Although TrackIr is a little more friendly to use. It's great that iracing does such a good job integrating them both into the sim so well.

This is amazing for content creation. I have seen many racing videos on youtube and what almost every content creator forgets is that the final video has to look good for the people watching. Everyone turns off the in game steering wheel, they use some really small FOV or they use VR which on video is always off from the center of the car and is motion sickness inducing. Even big creators make this mistake like Jardier. I understand that people set their game and settings up in a way that is best for them but as a viewer I want to see what looks good for me. I would rather watch a less interesting video that looks good than some low FOV or VR mess. This video is perfect. The FOV is perfect, seeing the ingame steering wheel is great, and the little bit headtracking just gives it that extra immersion. I honestly wish every content creator made their videos this way.

@@sirwinstonchurchill2052 It is very accurate and fully tuneable and yes you can pause it. It depends on the software you use to drive it in game. Put the view overlay on and you get a trace where your eyes are looking and you will see how accurate it is.

I wish track IR was cheaper. It's so expensive for what it is. I used to use something called an EDTracker which was basically just an accelerometer in a box on top of your headset and cost £20. But it made playing Elite: Dangerous and some other sims SO fucking good. Only had yaw/pitch, so could look around but could not roll the head or move it for/aft/left/right.

I drive only in ACC, but even there shared view with few others trying out TrackIR and giving up on it due impression that it's more annoying gimmick then useful tool, due too shaky/nervous experience with default configuration that moved/shook all around .. and felt probably .. like what watchers of streams of game played in VR feel. I "fixed" it by customizing TR configuration for game - removed all redundant axis, leaving just turning left/right, no leaning/lifting/swiveling; - added some deadzone in mid to prevent any stuttering/vibration inevitable from head micromovements - at very beginning of turning made it at very slow race, that gradually increases the more i turn head - bound one of buttons on steering wheel to center view With TR configured this way i still able to steady turn view to apexes, do quick glances to sides/back, but in "main head turning angle" movements are steady/non shaky "head turning" where/how needed with no parasitic/unwished movements. At this point i can tell that TR is more help then annoyance (unlike with default curves/all axis enabled). Note: unfortunately if using TR in ACC, free views cameras not working anymore, i cannot detach camera from car anymore in replays or eg. when i work as team engineer looking after teammate. Heard that VR users have similar problem in ACC.

I bought it once, used it for a few times mostly on ETS2 and sold it for the same price

i use the Delan Clip...bought to flight Copter in ARMA III but use it in IRacing too...i dont have the space or the GPU for a triple screen and that headtracking is quite good to look into an apex of a corner...without it even in training i loose lots of time because i dont hit the apex...but unlike Dave i use it only on horizontal axis...getting too wild if i use more than that

Seems like a good replacement for vr on paper. Only way would be on tripple screens. It might help a little but your not going to be looking at your screen on a single idk i havent tested but I don’t imagine it would be worth it with a single screen

Never tried trackIR but might try in some day, just went strait to VR but I preferer my triples over VR mainly because of heat in summer and I can just jump into my rig with no head gear. I also think it would mess with my visual reference of the car rotation, I like to look to apex without the car interior moving across the screen.

I Love track Ir, once I tried it I could never go back. I Play on a single screen single curved monitor. It improved my awareness and driving a lot. Budget alternative to VR, and It allows me to stay in tune with the 'real world' in the house. The Hat set up yeah...looks 'cool', but I use the alternative set up that clips onto my headphones. So yeah...love track IR. Does take a bit of testing and tweaking to get the values just right, so you don't feel unnatural with movement. For single screen simmers it's a must have.

TiR still beats VR by miles for comfort and convenience, which is the main draw for me. So much easier to throw on a hat or pair of headphones and go than having to get a box on your head, get it calibrated, load up the software for it, then open the sim and blindly crawl through the menus without being able to see your mouse and keyboard. I hope one day VR is universally as easy as "pop it on and hit play"

TrackIR definitely needs to be set up correctly with the software. Too many ppl just slap it on and complain that you need to turn your head too much to look around and look side-eyed. You can make it so you barely move your head to look side-to-side (couple inches at most), and a little more to look over your shoulder. It will seem too sensitive at first, but you will quickly get used to it. I've used it for 10 years and has kept me from spending money on every VR headset to come out. Will upgrade to VR eventually though.

On 3080 9900k 32gb of ram I have FXAA on and run triple 1440p and this track at the start 20 cars I'm getting about 65 to 70fps but my image looks much crisper. Not trying to that guy just thought it may be worth you looking into it and check your cpu and gpu usage with MSI afterburner because you've had similar issues in the past I've seen in other videos. Something seems off.

I got one and tried it. Gave up with it. Sometimes it would just flip out and go all over the place. My OMP seat has white piping so that might have upset it.

What do ya think, Dave? Have you been using these much since this video? The idea seems very interesting, and I would expect it may feel more natural than a fixed view on a single monitor setup.

Where are the days trackIR came out.....man this was the thing and still is ....in flightsim and simracing this is really the thing to have even when you have triple screens, now its collecting dust here since VR took the throne .

I’m using the 45 inches LG monitor curve screen, do you guys I think should get this device? Does it give me little improvement in term of avoiding accident in the race stuff like that?
