Since Feral Interactive have fixed up the OpenGL renderer in the Mad Max [ Steam ] Beta, here are some fresh OpenGL vs Vulkan tests.I already cleared up the issue before and included some manual testing, see here These new tests are re-done using their benchmark feature, which is unique to the Linux version. This should now give a much more accurate look at how OpenGL fares against Vulkan in some heavy areas of the game.Also, Feral have now made public how they have worked around a Linux performance issue. You might remember my post about tuning your CPU performance governor for Vulkan games , well this is partly where that came from (as well as Serious Sam). Essentially, to prevent the CPU performance being reduced due to less CPU use with Vulkan, Feral are spinning their rendering thread while waiting for the GPU ( see here ).Here we have a performance difference of between (approx) +6% to +15% when using Vulkan.Here we have a performance difference of between (approx) -20% to +45% when using Vulkan. Looks like there's an odd issue with Vulkan performance there, but I'm not the only one who has seen Vulkan sometimes do a little worse.Here we have a performance difference of between (approx) +3% to +11% when using Vulkan.Here we have a performance difference of between (approx) +1% to +6% when using Vulkan.Some thoughts: A fair amount of their time during the Beta so far has likely been spent fixing up the regressed OpenGL side and when taking into consideration Vulkan is considered "Beta", it's likely Feral has optimizations left to do with Vulkan.You might not think much of a 5% increase, but for people on lower-end hardware a 5% increase can mean a world of difference. I've seen a few people on GOL and Reddit say Vulkan has made it go from sluggish to smooth, which is a clear win.We also have to consider that the OpenGL renderer in the Mad Max beta has also seen some optimizations since the original release. The original release doesn't have the benchmark mode, so we can't test that in the same way along side the beta.Then there's also the drivers, Vulkan drivers are new and evolving and likely have their own sets of issues to be fixed. Some of which could affect performance. Sure Vulkan is supposed to have smaller drivers, but with so few Vulkan games out no driver has truly been tested.Be sure to share your latest results in the comments, I'm keen to see what it's like on your systems too.Finally, Feral are keen for feedback, email them direct here: vulkanfeedback@feralinteractive.com
