# Known Issues
## In-game Menu
In-game menu is a recent addition and may experience on certain condutions.
* On some system and game combinations, opening the in-game menu may cause the game to crash or cause graphical corruption (especially in Unreal Engine 5 games).
*Banishers: Ghosts of New Eden*
* Changing settings mostly tested but might cause crashes (especially changing backends or reinitializing backends).
* Some games do not release mouse control, kayboard & gamepag controls should still work in these situations.
## Exposure Texture
Sometimes games exposure texture format is not recognized by upscalers. Most of the time manifests itself as crushed colors (especially in dark areas).
*Shadow of the Tomb Raider*
In most cases, enabling `AutoExposure=true` in `nvngx.ini` or selecting `Auto Exposure` in `Init Parameters` from the in-game menu should fix these issues.
## Resource Barriers
The Unreal Engine DLSS plugin is known to send DLSS resources in the wrong state. Normally OmniScaler checks engine info from NVSDK and automatically enables necessary fixes for Unreal Engine games, but some games do not report engine info correctly. This problem usually manifests itself as colored areas at the bottom of the screen.
*Deep Rock Galactic*
Workaround is to set `ColorResourceBarrier=4` from `nvngx.ini` or select `RENDER_TARGET` for `Color` at `Resource Barriers (Dx12)` from the in-game menu.
## Black Screen with XeSS
Some users have reported that when using XeSS upscaler backend, the result is a black screen with UI. In some cases downloading the latest version of [DirectX Shader Compiler](https://github.com/microsoft/DirectXShaderCompiler/releases) and extracting `dxcompiler.dll`, `dxil.dll` from `bin\x64\` next to the game exe file resolved this issue.
## CAS (Conrast Adaptive Sharpening)
CAS added to XeSS backends to mitigate softness of upscaler, but CAS can also cause some image problems.
*Deep Rock Galactic*
1. Bloom removed
2. Hue is changed
## Performance Issues
* In general XeSS is heavier than FSR for GPUs so it's expected to be have lower performance even on Intel Arc GPUs.
* As a result of spoofing the Nvidia card to enable DLSS some games would use an Nvidia-optimized codepath which may result in lower performance on other GPUs.
## Display Resolution Motion Vectors
Sometimes games would set the wrong `DisplayResolution` init flag, resulting in excessive motion blur. Setting or resetting `DisplayResolution` would help resolve this issue.
*Deep Rock Galactic*
## Graphichal Corruption and Crashes
As mentioned above, spoofing an Nvidia card can cause games to use special codepaths that can cause
* Graphichal corruptions
*Talos Principle 2*
* And crashes, especially when raytracing is enabled.
