Any chance for PPSSPP getting better antialiasing independent from shaders like 8x MSAA/SSAA/CSAA/EQAA/TrSSAA. Plain old 8x MSAA and from post-processing AA 4x SMAA would be great improvement over blurry FXAA.

Right now, your only other option is some rough downsampling via the rendering resolution option. Works only with Buffered Rendering.

E.g. On a 1080p screen, set the rendering resolution to 8x for a SSAA effect. Clears up a lot of the jaggies at the cost of reduced performance and increased VRAM usage.

Alternatively, you can force MSAA from your graphics control panel but it'll only work with Non-buffered rendering. This is confirmed to work on both NVIDIA and AMD cards.

It works only in non-Buffered mode so you cant use MSAA in combination with shaders and driver forced AA is not reliable in general, MSAA/SMAA built in as option in emulator settings like with some other emulators would be far better. I have high resolution monitor so I dont need to downsample. Higher internal resolution is better than AA alone but higher resolution + MSAA/SMAA/SSAA is better than higher resolution alone. So I hope there will be more advanced antialiasing options in the future.

I agree with you completely on the matter, just wondering where you're coming from.

I'm sure this has already been asked for in the feature request thread.

Adding MSAA would add quite a bit of complexity to our already very complicated framebuffer handling code. Certainly not impossible, it will happen in the future but as our framebuffer code is going through a lot of change at the moment I'm pushing this work forward for now. Unfortunately, proper MSAA support is not just toggling a switch, you have to render to an extra bigger MSAA buffer and "resolve" it down to the original resolution every time a framebuffer is used.

Thanks for response great that MSAA will happen in the future. What about 4x SMAA its post-processing based but very good unlike other post-processing AA methods does it have difficulties with framebuffer as well ?
