Describe the bug
A few people noticed streaking artifacts around shadows and the screen borders in GTA4. They figured out that it gets fixed by turning ON Raytraced Bias Correction under the RTXDI section.
It turns out that they had used the LOW graphics preset in remix and the LOW preset sets this setting to OFF.
Not entirely sure if its an issue in every game or just IV.
On Marks suggestion, I've used a completely clean rtx config. Artifacting still happened.
It does not seem to be distant light related. It is also caused by sphere lights
How do you reproduce the bug?
- Launch any game (supposedly)
- Use the LOW graphics preset in the beginner remix menu
- Make sure Raytraced Bias Correction is off
- Notice streaking artifacts around moving shadows
If not reproduceable in other games:
- Install GTA4 and the 1.3.2 compatibility mod: https://github.com/xoxor4d/gta4-rtx/releases/tag/v1.3.2
You can skip installing the base remix mod and autopbr mod
- Open the game and use the low graphics preset
- You can adjust time via using the F4 menu, under Utilities -> time .. if needed
What is the expected behavior?
Turning off Raytraced Bias Correction should not result in streaking OR Raytraced Bias Correction should not be set to OFF in the low preset (or tweaked in combination with other settings)

Note: Don't mind the broken vehicles / colors. I used a clean dxvk-remix build instead of my fork with some required changes.

Turning off spatial reuse when bias correction is off seems to improve the artifacting:
