NatVak: It might be the grass shadow fix, it might not. It might be a function of your processor, your video drivers and/or your IGPU if Intel. It might be specific to DX9 or DX8.

Some possibly-related topics:

Ugly textures in ShoC and its mods -- use objects-only dynamic lighting or update video driver.

Solution to Intel dropping hardware support for DX9 in their integrated graphics cards found in 12th Gen (and up) CPUs and discrete Arc GPUs

NatVak: > i already reinstalled vanilla no mods

So, no grass shadow fixes?

It is possible that some setting in user.ltx has changed. You could rename it and then see what the game shows you when you start it again and reload a recent save. If it is different, compare the user.ltx newly recreated by the game with the one you renamed to see what was changed.

Otherwise I'd experiment with your video card's driver's configuration tool settings. There are some three- and four-letter-initial settings that work better with different GPU manufacturers. Maybe one of them is causing this effect.

Unfortunately I know very little about the graphics side of this game. Hopefully someone with more expertise will see your video and know what the problem is.

vlad_54rus: Looks like the typical bloom effect flickering due to it being rendered at a low resolution. Try this: open the console and type r2_ls_bloom_kernel_g 7

kahunaseal: wow amazing , it improved alot , the lightning lamp (as example ) at the beginning doesnt flicker that much still visable but so much perfect. ( i will add your suggestion on youtube as a fix)

i noticed something as well in the game , unsing nvg it causes double vision, any solution for this as well or other fixes you found out?
thank you so much you are a life savior.

vlad_54rus: Here is a nightvision tweak that removes double vision: https://drive.google.com/file/d/1bXCj2fcm6cRYFOF7EE9F2ZrQE7Av7-CF
