Hardware DirectX level stuck at v8.0

[Unix]

To fix this, try the launch parameter "dxlevel", e.g. -dxlevel 95. I think you need DX9 to be able to set shadow quality to high or to enable color correction. Note that using this launch parameter will reset video options for the game every time you launch it.

More info about it:
Valve wiki page (Ctrl+F, search for dxlevel)
Source issue #540 on GitHub[github.com]

To stop video settings from resetting:

Just run it once, exit, then remove the launch option, it will keep dx9 and your settings

Thanks a lot dude! It works perfectly with HL2, EP 1 and EP 2. :)

This worked for me. Still, sucks that it resets every time. Thanks for the help though.

Try to update to newest 320.49 Nvidia driver. It worked for me.

It occurs on AMD graphics also, so it doesn't seem to be a driver issue

So I can set the DX level. Still can't set the AA level to what it was.

Problem fixed since the last NVIDIA driver for me

[KiLLeR, eh]

ATI HD 4850, last drivers that were made for that series and I needed the fix. Thanks. Stupid Valve breaking a thing that worked and still hasn't fixed at least 2 months later in a public release.
