Source engine games limited to DX8

post #1 of 5
Thread Starter 
For some all my source games with the exception of portal 2 seem to be limited to DX8 only settings and im not sure why. I have a DX10 card so it cannot be hardware related (Battlefield:bad company 2 runs in DX10 mode).

I have tried using the console to set mat_dxlevel 95 but the game crashes after loading a level but it runs fine if i leave it at mat_dxlevel 80 but obviously it doesn't look very good.

Maybe try setting it to the appropriate -dxlevel in launch options? I know TF2 at least defaults to the last -dxlevel you used.

I have tried and it just crashes the games the second it finishes loading the levels.
