 ## Tips and tricks
 
+- If you see graphical issues in your games, add the environment variable `RADV_DEBUG=nohiz` as [recommended for BC250](https://elektricm.github.io/amd-bc250-docs/drivers/environment/#critical-environment-variables) as well.
 - You can adjust the kernel cmdline in `cmdline.txt` in the FAT32 partition.
 - You can adjust the VRAM size in `vram.txt` in the FAT32 partition. By default, it uses 512MB (0x20000000) which enables [Dynamic VRAM allocation](https://elektricm.github.io/amd-bc250-docs/bios/flashing/#why-flash-the-bios).
 - Monitor hotswap may work, but it will not change resolution automatically.
 - Some monitors have a black screen if a video=DP-1: parameter is set in `cmdline.txt`. Confirmed working without `video=DP-1:1920x1080@60` on:
   - MSI MAG274Q QD E2, DELL S2721DGF, DELL U2515H (1440p@60Hz)
   - Possibly also: LG 27GL850, Lenovo Legion Y27q, ViewSonic Elite XG270QG

 Many configurations, tips and tricks from the [AMD BC250 Documentation](https://elektricm.github.io/amd-bc250-docs/) also apply to PS5.
