I got 194 FPS at those daft settings on a 5700X3D + 7900 XT. Someone else got 210 FPS on a 5800X3D + 7900 XTX.
Seems both of us had massive VRAM usage (mine 18 GB, his 20 GB). Sounds like NVidia users aren't seeing crazy VRAM usage I think? Suggests the November drivers us RDNA3'rs are on are janky at best for this benchmark. I assume the 9070 XT benchmark leaker will surely have a more up to date AMD driver.
Really can't infer anything about the 9070 XT from this leak in my opinion.
AMD don't have as good memory/vram management as nvidia so amd will always use more vram in games.
