Created attachment 132023 [details] Steam main window Steam is no longer usable with mesa git. I suspect this is SI (Radeon HD 7970) specific though. Confirmed bad commit by reverting it. 2b8b9a56efc24cc0f27469bf1532c288cdca2076 is the first bad commit commit 2b8b9a56efc24cc0f27469bf1532c288cdca2076 Author: Marek Olšák <marek.olsak@amd.com> Date: Mon May 29 00:40:39 2017 +0200 radeonsi: move PSIZE and CLIPDIST unique IO indices after GENERIC Heaven LDS usage for LS+HS is below. The masks are "outputs_written" for LS and HS. Note that 32K is the maximum size. Before: heaven_x64: ls=1f1 tcs=1f1, lds=32K heaven_x64: ls=31 tcs=31, lds=24K heaven_x64: ls=71 tcs=71, lds=28K After: heaven_x64: ls=3f tcs=3f, lds=24K heaven_x64: ls=7 tcs=7, lds=13K heaven_x64: ls=f tcs=f, lds=17K All other apps have a similar decrease in LDS usage, because the "outputs_written" masks are similar. Also, most apps don't write POSITION in these shader stages, so there is room for improvement. (tight per-component input/output packing might help even more) It's unknown whether this improves performance.
