    Phoronix: RADV Lands Another Navi Optimization In Mesa 21.1 To Help With MSAA Performance

    The developers working on the RADV open-source Radeon Vulkan driver for Mesa are relentless in their quest for delivering optimal performance. Hitting Mesa 21.1 today were another set of patches for enhancing the MSAA anti-aliasing performance for GFX10 (Navi 1x / Navi 2x) graphics cards...

    enhancing the MSAA anti-aliasing performance
    Isn't that like ATM machine?

      So is RADV faster or is AMDVLK faster?

        While it varies, in my experiences it's usually RADV.

        Sometimes, though, RADV will be faster in regards to higher FPS but AMDVLK will have better frame times and a higher minimum and average FPS. That was my experience when benchmarking and playing Hitman 2 last year.

          When there's shader compile stutter with amdvlk-open, you think your PC is dying.

            Yeah, don't know why, but from my testing, it feels noticeably slower even than LLVM that mesa uses. Apart from a few games like Hitman 2, amdvlk-pro usually gives slightly higher fps and its proprietary compiler is much faster.

              Maybe because you need enable shader cache in variables?

                That's not needed anymore, it's gotten enabled by default.
                My gut feeling about compile times is like this:
                ACO: 1x
                amdvlk-pro: 2-3x
                amdvlk-open: 10-?x
                You could also measure the time for some games compiling shaders ahead. Though with games like Horizon Zero Dawn, you probably shouldn't schedule any appointments for the same day when testing amdvlk-open.
                I wish I were joking, but I'm just slightly overexaggerating at most...

                  With better MSAA anti-aliasing performance, your RPG games can now run much faster and you'll be able to perform much more APM per minute

                    Let me tell you about my 3.7 kdr ratio

                    I just thought of a good bumper sticker:

                    My kid has a higher KDR than your honor roll student's GPA.
