jeromeN7 Posted May 1, 2022 Share Posted May 1, 2022 The video setting "Reflected Shadows" causes stuttering when "Shadow Distance" and "Reflection Quality" are set to Ultra and/or Ultra+. The stutter issue gets really bad at dusk and dawn, but during mid day and mid night it's almost not there. There is almost no stutter if I stand still, but once I start moving it gets really bad. This sutter issue wasn't present in previous versions of the game. I play at 1920x1080. My PC is decent, Ryzen 7 2700x + 2060 Super, 16 GB of RAM. Temps are at 50-60 under load. I wiped all game data before updating to Alpha 20.4 (b42). I suspect this might have something to with this change: "Changed SkyManager to explicitly set shadowCustomResolution for the moon and sun lights based on the ingame "Shadow Distance" setting: 1k for Low/Medium, 2k for High, and 4k for Ultra/Ultra+. This gives more consistent results in terms of performance and fidelity when changing the setting, regardless of the user's output screen resolution."

pvtdragon Posted May 2, 2022 Share Posted May 2, 2022 I get this really bad, while in shadowed areas. I can go from 90fps on ultra setting to 20-30 in shadowed areas with major stuttering. I play at 1920x1080. My specs are: Ryzen 3800x, 2060Super, 32gb DDR4 RAM As stated before , this was not present in 20.3 stable. Link to comment Share on other sites More sharing options...
jeromeN7 Posted May 2, 2022 Author Share Posted May 2, 2022 My GPU usage is at about 70%, even when it's stuttering. So, my GPU isn't being overloaded, yet it's lagging like crazy anyway. Even with Reflection Quality on high and Shadow Distance on ultra+ it still stutters at dusk and dawn. When I say stutter I don't just mean low FPS, I mean very unstable FPS. It's jumping from 60-70 to 20-30 FPS many times per second. Metro Exodus with max settings is more stable, and that's saying something. I wonder if this would run and look better if the lighting system was completely replaced with global illumination ray tracing. Link to comment Share on other sites More sharing options...

I know what you mean when saying the stuttering. its like im playing a Gif image duing shadows. Its hard to explain, but the best I could come up with.
