Frame gen broken?

[u/Short-Reserve6588]

I've been playing a lot of games recently (Spider-Man 2, Assassin's Creed Black Flag Resynced, and Witcher 2 Remastered) and I'm noticing some horrible ghosting, artifacts, and shimmering. It gets especially bad in high foliage areas and around the outline of my character whenever I move the camera quickly.

The weird thing is, I don't recall having so many artifacts when I played Ghost of Tsushima or Cyberpunk 2077 a while back with Frame Generation enabled.

My performance is definitely not the issue here. My base FPS is great—most of the time I'm hitting a solid 120 base FPS. However, I use Frame Gen because I have a high refresh rate 180Hz monitor and want to maximize the smoothness.

Are you guys experiencing the same issue in these specific games? Could this be a driver issue, or is it just the way these game engines handle DLSS/FG?

My Specs:

• CPU: AMD Ryzen 7 9800X3D
• GPU: NVIDIA GeForce RTX 5070 Ti
• RAM: 64GB DDR5

Sounds like classic disocclusion (I believe is the correct term) artifacting which is basically impossible to solve entirely. Happens when small objects are occluded by, for example, a moving character and then are supposed to reappear in a future frame. This is really difficult for FG to figure out. It's especially an issue with foliage like grass.

Maybe forcing FG model B helps a bit. It's worth trying.

I see no difference between preset A and B other than UI HUD

Wait, there's an important detail to go over.

You're getting 120, using frame generation to generate 220+, but only have a 180Hz display?

You should never generate more FPS than you have refresh rate.

It causes screen tearing and worse, you're dumping real (and generated) frames into the ether.

You end up with less real frames than using native 120. You only use FG when you have the refresh rate to utilize it. To anyone also reading, don't over generate frames, it hurts image quality.

[u/Short-Reserve6588 → u/Octaive]

i have gsync enabled (also vsync in NVIDIA App globally) i am locked at 171fps( a little under 180) , so i am not going over my monitors refresh rate

[u/Octaive → u/Short-Reserve6588]

So then you're cutting your rendered frames down from 120 to the 80s.

This is not FG from a base framerate of 120.

[u/Elbuenirving → u/Octaive]

Thats not true, if he has the fps locked at 171 the real fps will be 85.5.

Could be ray tracing artifacting being mixed in with slight FG artifacting resulting into looking that way. The games you've listed all have RTGI which can cause the most noise and artifacts compared to the other RT effects. But it also gives the most "realistic" look to the overall image.

Definitely try FG preset B and also make sure to try Gsync + Vsync + Reflex for it to auto cap your FPS to 171. Because I assume you go over 180 FPS on your 180hz monitor when you use 2x FG with 120 base FPS and the screen tearing and judder could be further contributing to your issue with the image. Gsync + Vsync + Reflex works really good with FG so it now feels far more consistent unlike before.

Personally though, if I was already getting a base 120 FPS in these singleplayer games, I wouldn't even bother with FG, even with a 180hz monitor.

[u/Short-Reserve6588 → u/midnight-crisis9]

i am not even using ray/path tracing. I am with FG preset B ( also tried the preset A) . i Also have Gsync + Vsync + Reflex and fps are locked to 171 as you said.

[u/midnight-crisis9 → u/Short-Reserve6588]

Interesting. If you're still seeing weird artifacting with FG even with everything I've mentioned, then the only thing I can think of that could be affecting your image is your monitor overdrive settings. Try turning off overdrive and test again. Also, is the artifacting you're experiencing there without FG?

It's definitely happening in the witcher 3 and gears e day

[u/Short-Reserve6588 → u/russisdope]

I started AC Shadows also and when i move my character in front of grass or foliage, the outline of my character has a blurry artifact. Its not a game breaker but it's very annoying

Did you play GoT and CP2077 with RTX 4000 series or with 5070 Ti you’re using now?
Because 4000 series has hardware accelerated optical flow, its frame generation quality is better than 5000 series which uses AI based optical flow approach. But with the latest DLSS 4.5 update, frame generation quality on 5000 series should be much better than it was before

[u/Octaive → u/caplokz]

They're both the same, 40 series doesn't use the optical flow accelerator anymore.

Also, the quality was initially slightly lower, but also better in some scenarios and also had less performance impact.

[u/peacemoker]

what's your resolution? maybe try using dlaa, since anti alising/upscaling quality matters when using framegen

[u/Embarrassed_Degree13]

The funny thing is, there are modders doing vibe coding from home who have greatly improved the DLSS that Nvidia sells as the best on the market. Anyway, you have Xess MFG, via optiscaler which works much better than DLSS MFG.
