Current conclusion
On a 24 October Linux RTX 4090 experimental stack (main e13027a1f plus #9694 and #10388, local abe0d257a), Guardians of the Galaxy content 01.006.000 renders its main menu at about 1.7 FPS and reaches the first gameplay scene in Star-Lord's quarters on the Milano at about 1 FPS.
The menu's 40-present capture has median 586.7 ms/frame versus 133.7 ms of GPU busy time per present: the graphics recorder spends about 481.8 ms/frame busy while compute queue 0x23 is waiting roughly 92% of the time. The writer for the waited-on label is not identified, so the trace does not establish a fix.
Earlier merged #8991 on a different A/B build only reached first-level load before an AGC color-target CB metadata failure; neither result is a stable v0.1.3 full-game test.
Platform test results
Linux · Title screen and main menu render; New Game starts first level, blocked by another CB metadata error
IssuesUnpatched main stopped after ~4.5 minutes on compute shader 0x3b91c3e00 with GetImageResource dword 0 is not a valid runtime value. Patched branch correctly binds the two halves of the T# image-table record, reaches warning screen and rendered main menu, and starts New Game.
During cold shader compilation the warning screen progressed at ~0.3 FPS for several minutes; this is not a representative game benchmark. In the first-level transition another AGC graphics CB metadata error stops further progress.

Linux · Main menu at ~1.7 FPS and first gameplay scene in Star-Lord's quarters at ~1 FPS; long graphics/compute queue stalls
IssuesA 40-present menu capture records median 586.747 ms per frame (about 1.7 FPS), GPU busy only 133.690 ms/present, graphics queue 0x0 busy 481.8 ms/frame and compute queue 0x23 waiting 562.4 ms/frame (92%).
The same build reaches Star-Lord's quarters, where a separate profiling run reports about 1 FPS, many DRAW_INDEX_INDIRECT_MULTI and DISPATCH_DIRECT packets, and persistent WAIT_REG_MEM_64 stalls.
The separately enabled APS5_PROFILE_DRAW=1 measurements incur their own profiling overhead, so should not be merged into the 40-frame trace. Final 0.1s of graphics-queue events dropped (1,659 events); awaited label's producer remains unknown.
Build: Experimental local abe0d257a = main e13027a1f + PR #9694 + PR #10388; not tagged v0.1.3; 40 presents captured at frames 1150–1190

Known issues
Linux · Title screen and main menu render; New Game starts first level, blocked by another CB metadata error
- The shader-table fix is merged into current upstream main but not the tagged v0.1.3 release; gameplay beyond the first-level blocker has not been demonstrated.
- A later independent color-target metadata error remains, so reaching the New Game load is not an official Playable result.
Linux · Main menu at ~1.7 FPS and first gameplay scene in Star-Lord's quarters at ~1 FPS; long graphics/compute queue stalls
- The menu and first level render at roughly 1–1.7 FPS on this local patch stack; gameplay performance and renderer scheduling remain severe blockers.
- The source does not identify which producer wakes compute queue 0x23, and the final frame's graphics-queue trace is incomplete; a causal fix is not demonstrated.
- The test uses main with two additional PRs and differs from both the earlier PR #8991 base and official release v0.1.3.

PPSA01748, content version 01.006.000. Earlier merged PR #8991 reached menu and first-level load before another graphics error; the newer October 24 menu/quarters sample uses main e13027a1f plus #9694 and #10388 and therefore measures a different experimental stack.
