Linux · Uncharted 4 first gameplay chapter (boat scene); default prebuild exhausts host memory
- Build / branch
- Linux developer build: eager shader-library prebuild compared with APS5_NO_LIBRARY_PREBUILD=1
- Hardware / OS
- Linux; RTX 4070 Ti SUPER (NVIDIA 615.78.08); 32 GB system RAM
- Reported
Observed result
The reporter reached gameplay in the first chapter. With registration-time shader-library prebuild enabled, process anonymous memory was 11–13 GB and pipeline cache files 661 MB, and the 32 GB host ran out of memory during the chapter. With APS5_NO_LIBRARY_PREBUILD=1, the same report measured about 7.5 GB anonymous memory, 72 MB per-run pipeline cache, and continuing gameplay.
Blockers & limits
- On this NVIDIA host, eager pipeline-library preparation consumes several GB beyond the disabled-prebuild run, eventually exhausting the available RAM.
- The opt-out is a tested per-build mitigation; the report does not establish identical behavior across GPUs or official release builds.
