Yeah I’ve never been a fan of overlays either, it’s only since becoming a “streamer” through peer pressure I’ve needed them at all, and only conceded to using them with all the talk of Windows improvements to allow them to work better.
I did follow the advice on the DX dev blog, to start with it felt as though toggling FSO on the compat tab wasn’t doing anything at all, but after doing the other steps and trying it again it definitely made some difference.
So my current “fix” to get back to pre 1.5.4 performance in 4k;
Removed the Xbox Overlay and MS Overlay systems as described above - stops overlay crashing and improves stuttering and laggy feeling.
Opened the DT Launcher settings, reset them, and turn everything off/disabled, native res, default threads, start the game and close it again - this was just to help with the problem solving initially, as it rules out all the up scaling tech etc but it seems to make the rest go more smoothly so I’m leaving it in.
Disabled Shader Caching entirely through the nVidia Control Panel or AMD Adrenaline, I chose to disable it system wide but doing so just for Darktide if you can should be fine.
Deleted Dartktide shader cache files - this with the previous step reduced stuttering significantly and helped with the bad LOD pop.
Disable Full Screen optimizations on Darktide.exe - cleaned up last of the stuttering.
Start Darktide and check performance.
If all has gone well you should have a nice jagged FPS and frame time graph as you look around the Mourningstar, but with no spikes or flat spots, no stutters or hitching, and minimal LOD pop.
(I also removed a bunch of the other crap that comes with Windows like Edge, Office, Cortana, widgets, themes, the rest of the Xbox ecosystem, basically anything that isn’t actually needed for the PC to work - this was an instant performance boost in general.)
Here is what wiggling the camera looks like in roughly the same place as before with minimal settings in native 4k, I don’t have any of the lag, stutters, hitching, tearing, or texture pop in that I had previously, and the graphs are far more “natural” looking if that makes any sense.
Turning on DLSS, again wiggling back and forth in roughly the same place with the above changes (and back in Default “High” with RTX enabled!) gives the expected performance boost and no longer causes such awful stutters or LOD pop, there is still an almost imperceptible input lag compared to no DLSS but I expect the majority of people would never notice.
There were still a few things popping (the seals on some distant surfaces) but this is the same as pre 1.5.4 so I bumped mesh up to 3.0 like I had it before and that was enough to stop it from catching my eye.
Not tried FSR yet (I used to use that over DLSS due to the input lag), gonna spend the rest of today playing/streaming then mess around some more tonight.
Looks soooo much better, all the textures are present and correct, the frame rate is stable and it performs as it should!
