I have this problem when every time I get shot my screen turns grey, the more damage I take the more grey my screen becomes. I'm using Blackfires 2 mod v1.10 along with MaldoHD v4.0, Qmod v1.91 and Classic mod v2.9. I also have the DX11 and the HD texture pack. Below are some screens, my system specs and the commands in my autoexec.cfg. This issue is pretty game breaking. I hope someone can help.

Do you have the issues without using MODs?

If the problem occurs without the mods loaded, than it might be a driver issue. Try using an older whql driver or try out a new beta driver.

No, the problem is not there without the mods loaded, but I will try updating to the beta driver and try it again.
