    Phoronix: DXVK Developer Working On New "AGS" Experiment For Possible Performance Benefit

    DXVK lead developer Philip Rebohle is experimenting with "DXVK-AGS" as a new exploration project to see if it makes sense implementing AMD AGS SDK support within DXVK for this Direct3D 11 to Vulkan translation layer...

    Every percent is a percent faster!

      I'm very curious if this actually works with Crossfire setups in Linux without requiring the user or other drivers from doing anything else. If it does, I'm pretty sure that would be the first working example of open-source multi-GPU rendering working under Linux.

        And here we have yet another benefit from using hardware made by company that supports open source software.

        Oh...cool...just checked and I actually have a game that contains the amd_ads_x64.dll -- Hitman 2....what sucks is I've yet to build a custom Proton that will run Hitman 2...it works damn well with Steam's 4.2 Proton. I'm sure y'all can guess at least one of the items on my agenda today.

        EDIT: Tried Hitman 2 with ads built from all three versions and I didn't have any luck getting it to run.

          That Crossfire part peaked my interest too. Will be interesting to see what comes of it.

            Current code have only Depth Bounds and Multi Draw Indirect APIs implemented.

            Edit: I wouldn't hope for any CrossFire work here, but Multi Draw Indirect should give good performance boost for games that use it properly.

              Anything that gets Linux as fast or faster than Windows is what we need.

                The developer commented on this over on Reddit to clear up any confusion/expectations:

                Sigh. Since people (especially over at Phoronix) are already expecting way too much: - No, this does not and will notsupport Crossfire. - No, not every game shipping an amd_ags_x64.dll actually use the supported extensions. Many games just use it for HDR setup, driver version info, and the aforementioned Crossfire. - No, this won't magically make your Nvidia card run 200% faster. Might work on non-AMD hardware by accident, but it wasn't tested. - No, the performance gains are not significant.

                  FWIW, I wasn't expecting too much. Anything Crossfire+Linux will make me raise an eyebrow since that's one of the things we don't have.

                  I expect some sort of DX12/Vulkan any-GPU setup for us eventually, maybe...

                    Well I don't think crossfire or SLI is a common choice for most of us. So this new proj won't help us a lot. But it's still exciting to see another great feature deployed under linux.
