Doom vfr gtx 960 1080p#

Vulkan does generally improve minimum frame rates, and only the 950 shows a clear drop in minimum fps. The 2GB 960 also shows a small drop, and interestingly the 1060 does as well-perhaps the 368.64 drivers aren't fully baked, or it might just be variance between runs. We do see a few performance regressions, and the GTX 950 shows a nearly 10 percent drop with Vulkan.

The GTX 1080 performance goes up by 20 percent, the 1070 improves by 10 percent, and most of the remaining cards fall within the margin of error. In contrast to AMD's hardware, Nvidia's showing with Vulkan is a lot more mixed. Testing the same card at the same settings multiple times gives a variance of around four percent, so anything less than that can be considered equivalent performance-not that you'd really notice anything below ten percent anyway. I do my best to run the same path each time, but there are minor variations depending on where the demons show up. Basically, I play a 150 second sequence (give or take) where I run though a section of the game and fight a bunch of hellspawn. One thing to note is that my Doom benchmark sequence uses FRAPS for OpenGL and PresentMon for Vulkan, and there is a bit more variance between benchmark runs than some other games.

I could have also tested at 1080p High or Medium quality, but the gains in performance aren't all that great and at some point I had to draw the line and simply finish the testing. (Trying to put everything into one chart just resulted in a massive pile of results that ends up not being particularly readable, though if you're interested, here are the full 1080p, 1440p, and 4K results.) I'll discuss each chart in turn, starting at 1080p.

For the charts, I've separated each resolution into AMD and Nvidia hardware, and colored Vulkan results red and OpenGL results blue.
