The NVN2 front end and the SM86 to Maxwell shader lowering (tools/xlate/AmpereLowering.cs, mesh and task stages, bindless texture pools, BRX jump tables, the NVN2 compute c0 layout) with four translator patches (0017-0020) bring the opening of the game to 58-60 fps on the Vulkan renderer. This round fixes the haze: SM86 IPA is lowered as a plain Maxwell IPA.PASS (texture coordinates were corrected for perspective twice); LDSM, TXD, both F2IP byte forms, HMMA, MOVM and HFMA2.RELU are lowered and spill mode has eight uniform register groups; conditional rendering keeps the newest counter report per address and treats a report as pending until its value is in guest memory, so occlusion tests and the depth clears around the depth copy behave; and the upscaler stand-in decodes the post pass's sRGB picture before writing the linear target. Tensor-core programs keep the stand-in unless NX2NAVI_NATIVE_TENSOR=1, because their lowering does not match the hardware yet. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
