[CS1.6] Cannot force anti aliasing

[eakzoor]

Running game at 800x600 (Fullscreen 4:3 with black borders). I can make it work with -nofbo

What is forcing anti-aliasing?

[JoiNNN]

Forced AA from Video driver Control Panel, such as NVIDIA Control Panel... For me with an nVIDIA GeForce 9800 GT works tho.

[dscharrer]

I can reproduce this with AMD drivers on Linux (at least with Catalyst 12.8 - ancient, I know) and the equivalent option enabled in amdcccle. I am running the game fullscreen, at my monitor's native resolution (1920x1200).

Forcing anti-aliasing this way used to work when HL1 was released for Linux (and also works in pre-Steam HL1 under Wine). I can also confirm that it works when using -nofbo - did HL1 render directly to the back-buffer when running at the native resolution back then?

This obviously applies to all GoldSrc games.

When setting amdccle to "Use application settings" there is no anti-aliasing in GoldSrc games either, but other bug reports and the -nomsaa options suggest that there should be.

Example where aliasing is clearly visible:

This might also be a duplicate of / related to issue #892.

Can you add "-directblit" to your command line and tell me how that helps.

[alfred-valve]

Okay, that is the issue, if your card didn't support GL_EXT_framebuffer_multisample_blit_scaled then it (incorrectly) disabled the MSAA backbuffer. Setting "-directblit" would work around this. Using your video card driver to force rendering modes isn't supported and won't work (by design) with the current HL1 engine.

I can confirm this bug with NVIDIA. "Use my preference emphasizing: Quality" in NVIDIA control panel

I'm using "-nomsaa" to avoid fps drop in smoke. -directblit or -nodirectblit doesn't help: -nofbo helps

[alfred-valve]

Using -nomsaa will also cause this issue, so don't do that @MaxKorz . Using -nofbo goes back to the older rendering system that lets the nvidia controls inject themselves. So don't use -nomsaa and do use -directblit

[ghost]

yeah, -directblit without -nomsaa fixes the issue, but without -nomsaa I experience low fps in smoke... C'est la vie

[alfred-valve]

Try setting the gl_ansio cvar to different values (try 4 rather than the default 16), that may help your perf a lot with a smaller graphical impact.

[ghost]

no, gl_ansio 0/2/4/6/8/10/12/14/16 in Launch Options - I see no difference
