This leaves us with a 2% performance gain in Quake II RTX: Totals from 7 (14.00% of 50) affected shaders: VGPRs: 720 -> 688 (-4.44%) CodeSize: 213052 -> 212980 (-0.03%); split: -0.05%, +0.02% MaxWaves: 67 -> 70 (+4.48%) Instrs: 39429 -> 39394 (-0.09%); split: -0.15%, +0.06% Latency: 1096258 -> 1096943 (+0.06%); split: -0.05%, +0.11% InvThroughput: 230661 -> 222963 (-3.34%); split: -3.42%, +0.08% VClause: 1208 -> 1206 (-0.17%); split: -0.25%, +0.08% Copies: 5321 -> 5269 (-0.98%); split: -1.22%, +0.24% Branches: 1903 -> 1902 (-0.05%) PreVGPRs: 650 -> 645 (-0.77%) Reviewed-by: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> Part-of: <https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/21470>
