GravityMark OpenGL/Vulkan Performance For NVIDIA RTX 30 vs. AMD Radeon RX 6000 Series

1080p testing tends to not be very interesting for benchmarking modern high-end GPUs, but for those curious here are those metrics first with the Vulkan renderer. For the 1080p Vulkan performance the AMD RDNA2 performance was coming in short of expectations with the Radeon RX 6800 XT only hitting the NVIDIA RTX 3080 Ti.

But when using OpenGL, the RDNA2 GPUs with the RadeonSI Gallium3D driver really shine.... Even the Radeon RX 6800 came out ahead of the GeForce RTX 3090! It would be fun to see how much further ahead the RX 6900 XT would be in this case, but alas I don't have that card available for testing.

At 2560 x 1440, the OpenGL version of GravityMark was still heavily favoring RDNA2 on RadeonSI with the Radeon RX 6800 XT outperforming the GeForce RTX 3090 but by slimmer margin and the RX 6800 now just behind the RTX 3090.

When running GravityMark with Vulkan, the NVIDIA performance is in the much stronger position. For all of the graphics cards tested, using the Vulkan API was leading to much higher frame-rates than using OpenGL.
