UE 5.1 re: Stalker 2 - need some help

Summary

I understand this may not be the best place to report this and/or seek advice, but I’m desperate to get this fixed. Graphical ghosting is the best way I can describe this. I’m not sure the correct term because ghosting as I understand it is essentially tracers left behind when an object is moved on your screen. These are stationary giving almost a double vision effect. When an object is in my direct field of view or in my crosshair, it does not have this effect.

Troubleshooting steps taken:

DDU fresh install of drivers, changing Nvidia control panel settings to force certain settings to be more UE friendly, custom engine.ini in game files, tried every combination of upscaling with and without frame gen.

Hey there @Achlimed! Welcome to the community! You’re correct that this forum is not the ideal location, as it’s primarily geared towards Unreal Engine developers, as most fixes that I could give would require you to have access to the game files. However, if we can ascertain which component is causing this we may be able to come up with a workaround.

Ghosting like this can stem from a handful issues in engine.

Lumen ghosting
Temporal Anti-Aliasing ghosting
Denoiser ghosting

For Lumen, most fixes require you to access the game from the editor or be able to access the console or other Cvars. If you can access the developer console, you could use r.DynamicGlobalIlluminationMethod 0 but the fallback may not be great.

For the Anti Aliasing, I’d recommend adjusting the AA settings in the game’s settings and see how it reacts. Non-temporal methods shouldn’t have the issue at all if this is the case.

For the denoiser ghosting, you will once again need to be able to access the console, this doesn’t look like it’s coming from the denoiser due to the limited ghosting but I’d be remiss to not mention it. The command to correct this (will also make shadows look bad if it was in use) would be r.Shadow.Denoiser 0

If none of these work out or you can’t access the console (which is possible since it’s a shipping title), you may need to report the issue to the developer.
