Certain Games Have Non-working Anti-Aliasing (Sourcemods, GTA San Andreas Renderware, Flight Simulator X, etc)

I have an Intel i3-12100F and RTX 3080 gpu, for some reason after some time playing I noticed that even though I turned AA settings and overriding them with Nvidia control panel options, jaggies are still there. The worst offender is Sourcemods and GTA SA, where it doesnt really matter if you set high AA or no AA at all. But nonetheless pretty much all games that I frequently play suffer from this.


Already tried uninstalling driver using DDU and it didnt work..Is there any reason why? I hope it aint because the "GPU's so powerful it cant process AA in older games".

Yes, there is a reason, but it's not about processing speed, but capability.

Not all types of anti-aliasing work in all games.

Supersampling almost always works, but it's performance demanding.

MSAA and similar work well with most older games, but they miss certain transparency objects (need transparency AA paired with it to get them) and don't work well with new games.

TAA works a lot of the times, but has tradeoffs, such as "ghosting" on slow moving objects, or reintroduction of aliasing in motion.

FXAA... well, it exists. It's more of a vaseline filter than antialiasing and I can almost never tolerate it (at least on its own) but it usually has an effect and you might find that preferable to jagged edges.

In the opposite direction of supersampling is upscaling/DLSS/FSR, as well as AA modes using the same type of tech, such as DLAA (not sure if AMD has an equivalent yet).

Usually "control panel enforced" is traditional methods like MSAA and that doesn't often work, especially with newer stuff (and by "newer", this can mean stuff from the 2000s and onward; Halo CE with deferred rendering was sort of the first "big" title to not be effected by MSAA I think).

maybe its because of driver issues? Or Nvidia quietly deprecates older AA techniques? I mean I do play old games quite a lot. I swear this only happens after I used this card and a 3060M laptop which I also had to DDU'd.I never had any issues with older Geforce GPUs (not so really old like the days of 900 series but I do once used 1080 as temporary GPU before getting 3080).

Some methods do get deprecated (CSAA comes to mind), but that example happened with new hardware not supporting the modes, not the drivers.

Most of the time, it's simply the games themselves. MSAA, which is the one the drivers try and force as far as I know, is one that doesn't work with a lot of modern games.
