DLSS Frame Generation doesn't work on 1080p

Performance

Issue Description (Required):

I know the title sounds a bit odd but for whatever reason DLSSFG does not work when I set my game resolution to 1080p (my monitor’s native resolution). Frame gen works on resolutions below 1080p and above 1080p, but if I set it to 1080p FG starts to become very choppy (140~fps feels like 50fps).

I have tried:

  1. Switching from Fullscreen to Windowed to see if FG works
  2. Lowering/raising settings to see if it changes anything
  3. Tried using user Vizra’s 2 fixes for fullscreen enabling and texture streaming (also tried with both fixes disabled)
  4. Verifying game files

Occasionally DLSSFG does work on 1080p but I have done nothing differently when booting my game to see what could be causing the problem.

[PC] Do You Use Mods? (Optional):

We are looking in to some issues pertaining to Frame Generation - I’m waiting to hear back from our QA department about this.

I apologise I don’t have any immediate solutions, but I hope it can settle your concerns knowing it’s on our radar!

Okay, so I may have stumbled upon something on accident but it appears that DLSSFG works in 1080p when I’m using Special K with a local install. The only difference between using a local Special K installation and just playing the game normally is that the Special K install is done through a custom wrapper .dll file.

Not entirely sure what else is being done by the .dll file but DLSSFG works perfectly fine while using Special K with no noticeable loss in displayed frames compared to a non-Special K boot.
