The one thing GZDoom may gain from Vulkan is multithreaded processing of the data, and maybe - that depends on how its texture management works, keeping stuff preprocessed per sector. What's making this DOA right now is that it's impossible to bstch draw calls with different textures. If Vulkan does not solve this in a general fashion, there's not much that can be done to optimize the renderer.

I haven't and my Google-fu is failing me.

Me too. I hadn't realized that Intel cripples Pentiums by disabling SSE/AVX instructions and took me a while to find out why my Penryn laptop couldn't run a SSE4.1 binary.

Gzdoom and Zdoom performance improves linearly with the hardware but due to increases in resolution Zdoom becomes exponentially slower!

Well that sounded dramatic but you get my drift.

While true, it wont happen for awhile. We've hit a limit on single core speed until heat distribution can be improved.

How much of a difference would it make to go from 2.66 to 3.17 Ghz? Now that winter's around I might just OC my ol' Q8400 again back to the maximum supported speed on this chipset.

On a completely CPU-limited application, assuming that speed increase is linear and not affected by other effects, slightly less than 20%.
