@@you2be839 well. It's a new frontier. People dunked on DLSS1 for a good long while. This would be great for improving experience at high fps if we can get the vsync and game capping better controlled. I would love a 50 actual boost to 100fps locked. The game would play smoothly and not turn my computer into a toaster for 3rd person action games, for instance. Obviously not applicable for eSports, but those games are rarely dependent on modern tech anyway, outside of Reflex.

I think external vs internal framerate limiter might be interesting to look at regarding input lag with dlss 3.
17:15 the high visibility of these flickering artifacts around spidey's legs could also be explained by the contrast between the suit and the extremely bright sun reflection. On the other hand the fairly large reconstruction of the brick wall texture is a different beast altogether - the spot is filled with pixels very similar to the surrounding texture, hence you can't see it during 120 fps gameplay. It's the difference between picking an average color to fill a hole and drawing a new outline for important geometry moving against a contrasting background.

01:56 You can try to use some losless Codecs to record like UTVideo. Most of them are CPU only and Multithreaded. They have almost no performance impact (since almost no compression is happening), but require a lot of disk space since (at 1080P) they produce 4-7 GB/min. I used this method for almost 8 years for my YT Channel and the resulting quality (at the time) was always A LOT higher than NVenc. The mentioned "frame dropping" should be a result of either the Nvidia Hardware or the current implementation in OBS. This problem is especially annoying if you stream to KZread via HLS which results in the exact frame dropping you described.

Unless the game is reading your mind, I don't see how it could possibly do this accurately and consistently.
23:08 If you look at the label on the bar "El Coyote" - its darker on the DLSS3 side just like DF mentions earlier in the video. Also, the place where bottles are on shelves looks darker. Same with the ceiling lamp in the middle where the brightness is different. This might reduce contrast in some scenes but probably unnoticeable otherwise. Also look at the Dart board? circle next to bartender - that area looks differently lit in DLSS3 vs traditional. However if you look at the middle seat where no one is sitting - the contrast is not lost w.r.t its surroundings. Brightness reduction is most apparent on the skull above the bar. DLSS3 needs work for sure.
Beautiful breakdown. Also like how Alex's hair got combed down towards the end of the video hahaha
Outstanding quality of video ! BRAVO !!!!!! Incredible stuff DF !!!
Phenomenal work! Highlighting specific areas where DLSS 3 can falter is very useful for discussion, and helps to bridge the gap between the subjective (i.e. what we "notice" in the image) and the quantitative (what we can actually "measure"). I did have a question regarding screen-tearing, G-Sync and latency though. When using DLSS 3, would screen-tearing issues be resolved, and the latency penalty reduced, if you: 1. Enabled G-Sync in the control panel, 2. Left V-sync off in the control panel, 3. Capped FPS using an in-game limiter or RTSS, below the max refresh rate of your monitor? (e.g. 118 FPS in your case) My thinking here is the omission of forced control panel v-sync would remove an extra layer of latency, while an FPS cap would still keep you within the G-Sync window. Of course, I'm not sure if this also breaks normal G-Sync in the process?
@HeloisGevit
Жыл бұрын
I can't speak for DLSS3, but I know that using GSync while Vsync is Off results in tearing at the bottom of the screen, with or without a framerate limiter, even when remaining within the GSync window. The only way to eliminate tearing entirely is to enable Vsync. Without DLSS3, you'd want GSync + Vsync + Cap FPS around 3 frames below your refresh so that, like you correctly stated, you remain within the Gsync window and don't experience Vsync latency. But as Alex has demonstrated, that's not applicable with DLSS3.

Ah cool, thanks for the clarification. Even though Alex mentioned it in the video, I wasn't totally sure if V-Sync was always a prerequisite for G-sync to work, or if this only applied when DLSS 3 was active. I've never owned a G-sync monitor, so this is actually surprising to learn. On my freesync display, I usually just make sure the game is running in Borderless and freesync kicks in just fine.

Hardware Unboxed found that DLSS3 frame generation heavily breaks dynamically moving HUD elements on screen, like player names in "F1 22" or POI markers in "Microsoft Flight Simulator". In those cases they come across as major issues and are extremely distracting. What sucks for nvidia is that they don't support DP2.0. So no 4K 240fps, although that would be the most viable target. at lower FPS it breaks apart a lot, at higher frame rates outside of the displays refresh range you need to contend with tearing... And once we see 4050 and 4060 cards, frame generation will make even less sense due to the lower framerates.
Amazing video, the only thing I don't understand though is why you would turn on VSync at all anymore if the ultimate aim is to have settings heavy enough to stop the game from exceeding your monitors maximum refresh rate? The lower latency of VSync off is a win and if the aim is to never exceed the monitors refresh then you won't have tearing above say 120hz, so why even enable it? Thanks again for the amazing video.
@jsVfPe3
Жыл бұрын
You'll still exceed the refresh rate sometimes, and the VSYNC only comes into effect when you hit the 120 FPS mark. So you're choosing between having occasional periods of higher latency when you are at or above 120 FPS, or periods of tearing. The tearing would be more noticeable for me and I'd do the same as Alex, but it may depend on the game and the person.

@@jsVfPe3 True, the only reason I'd probably leave it off is the extra 5ms latency you gain back by having it off when even below 120hz, like you can see on Alex's graphs at 28:51 for example. I know it's a tiny gain but I'd probably only enable VSync for games where I know I'll be getting crazy high framerates about 120 such as CS:GO, etc. Most of the games I'd expect these crazy frames in won't have DLSS 3 anyway so I'd just use the in-game VSync toggle on a game per game basis.
This is incredible. I can't begin to fathom the amount of effort that must have gone into both researching the data and making it presentable to the general (admitedly somewhat enthusiast) public.

I wanted to thank you for this analysis Alex as I noticed the same panning issue in A Plague Tale: Requiem. Forcing Vsync in the Control Panel cleared up the issue. Top notch job!
Now that's REAL tech stuff we expect from DF and Alex in particular. Extended inspection of scenarios with nearly-scientific precision.
Really important thing to note: Keep in mind that if you have both G Sync and V Sync active and your FPS is at your monitors refresh rate you will have only V Sync active and that will increase your input latency pretty heavily. Yes, it is recommended to have both G Sync and V Sync active (for no tearing at all) as long as your FPS is below your monitors refresh rate (recommended to limit your FPS with RivaTuner). The reason why it's recommended is because while having G Sync active (below your monitors refresh rate) the downsides of V Sync's higher input latency are mitigated by G Sync (as long as you don't reach your monitors max refresh rate). In conclusion I wouldn't recommend having V Sync forced ON globally because it might negatively impact your experience in some games, especially competitive games that usually have higher FPS and can easily reach the max refresh rate of your monitor. What I personally do is activate V Sync on a game by game basis while having G Sync active for all games (since G Sync will not affect input latency in any way). And sometimes limiting my FPS slightly below my monitor refresh rate for a zero tearing and no additional input lag experience in cinematic games. PS: Regarding 31:00 in the video. Yes, Riva Tuner is enough to reduce the input latency *as long as you limit your FPS slightly below your monitors refresh rate* Ex.: Max refresh rate is 144Hz, I limit my FPS to 138 or 140 FPS.

Fantastic Analysis! I'm still poking forward to see how this performs for productivity apps.
The insane work here is really appreciated.
Awesome video, thank you! The final summary is great, showing the scenarios where DLSS has issues but also where it can truly shine like Cyberpunk at 4K RT on, truly impressive. Thinking this will be very useful in the future Witcher games in the coming years, where having maximum visual fidelity improves the experience a lot.
Top-notch work, Alex. Keep it up.
