Map used is Daybreak from the steam workshop: Takeaways: -Vulkan has better GPU utilization -Vulkan utilizes more VRAM than DX9 -DX9 has better framerates when there isn't a lot of action but Vulkan runs better during intense scenario's like hordes (somewhat lines up with what valve got with Dota 2) PC: CPU: Ryzen 7 7700 With PBO enabled RAM: 32GB DDR5 6000 CL30 (Tweaked timings) Storage the game is on: Samsung 980 pro 2TB GPU: XFX MERC 319 RX 6800 16 GB OS: Windows 11 24H2 Video settings: Antialiasing: 2x Texture Filtering: 16x Shaders: Very high Models and textures: High Effects: High Vsync: Off (no shit) Memory pool: High Multicore: On Resolution: 1920x1080 Utilized Demo playback to remove server overhead when running locally
