ASTRONEER (PPSA27623)

[JJenkx]

Tested ASTRONEER (PPSA27623) 01.015.000 natively on Linux 7.2.9 / Ryzen 9 7950X / Radeon RX 6650 XT, RADV Mesa 26.2.4. Unreal Engine 4. Short bring-up check.

Result

On plain main 61d0fa5b3c the title runs without a driver stop through the System Era logo, "Loading Solar System" and the opening cinematic. It runs at about 1 FPS: in the 100-120 s window, frame p50 is 1099 ms with the GPU busy 90 ms per present. The draw thread spends its time copying guest buffers into staging on every draw (GuestBufferMemory::copyRegion → GuestMemory::Read), because host imports are refused on this machine.

With main 61d0fa5b3c + #8091 + #6959 the same scene runs at frame p50 71.8 ms (12-19 FPS). The intro shows:

• the forest,
• the orbital station and the drop pod,
• the descent to the planet,
• the pod landing on the surface.

The image is at normal brightness. With #8091 alone it is very dark: UE4's 32-slice colour-grading LUT exceeds RADV's maxMeshOutputLayers = 8, the same cause as #6933 and #8613.

What it needs

• fix(agc): lower import budgets only on memory exhaustion #8091: host-import budget handling. Measured with APS5_TRACE_SECONDS=100:20, same machine and scene: p50 1099 ms → 71.8 ms.
• fix(agc): render layered mesh targets within device limits #6959: colour-grading LUT brightness.

Not verified

Gameplay after landing (no input was given past the intro), audio by ear, save/load, and long sessions.

AI-assisted testing and report: yes, Claude Code.
