Hi, y'all! A small patch again, but potentially huge for owners of older NVIDIA cards. [list] [*] Improved rendering performance on NVIDIA GTX-series graphics cards [/list] We had an oopsie. Somewhere in the middle of last month's optimizations, we missed a performance regression on pre-RTX cards. As a result, owners of e.g. GTX 1080 Ti have been getting terrible performance, in the ballpark of 40 FPS, and it would not get better with lower screen resolutions. That should be greatly improved now. Older GTX cards should see a boost as well. 🥳 This required some plumbing work, so please let us know if you experience any new graphical errors or corruption. FWIW, we've tested on RTX 3080, RTX 2080, GTX 1060, GTX 760, RX 6800 XT, Vega 5, R9 270, Arc A380, and UHD 630, so it should be fiiiine. [i]Notes for nerds: turns out that if you use "vkCmdDrawInstancedIndirectCount" on pre-RTX NVIDIA hardware, you'll be paying a hefty price for that "maxDrawCount" parameter. Wish I had known before changing most of our rendering to use it 😛 RTX, GCN-generation AMD hardware, and even Intel UHD were all fine with it, but we've failed to benchmark older NV.[/i] Cheers, Tom P.S. Thanks to LordMustang for help tracking this down 💕
