[Withdrawn] Test build: streaming and GPU coherence fixes (on 0.3.3)

Warning

Withdrawn: do not use. This build removed the GPU merge, which fixed the London pub crash but cost a lot of frame rate (44 → 27 FPS reported in Supermedo#115). 0.3.6 fixes that crash without the cost, and short reads are handled there too.

Use 0.3.6, or to test the file I/O change on top of it: guestio-1274d36.

---

Unofficial test build, not a release from SuperMedo. It replaces two files of 0.3.3; everything else stays.

Built from fix/gpu-merge-coherence (commit f8cfb3b), which contains:

• Complete file reads into game memory (fix/guest-writes): a read could stop short without an error while GPU page tracking protected the destination (Supermedo#101), which fits the Uncharted 2 streaming crash (iSubMesh < m_numSubMeshInstances, white textures). Also fixes split flexible memory freeing pages still in use.
• GPU data reaches game memory before the game can read it: the "merge" shortcut let the game read stale data; BB_GPU_MERGE=0 was the workaround for the Uncharted 3 London bar crash (Supermedo#124). The shortcut is removed and the correct path waits only for the GPU work that wrote the page.

Install

1. Back up bin\bb-probe.exe and bin\libc++.dll in your uncharted-windows folder.
2. Extract the zip into uncharted-windows, overwriting both. (libc++.dll is a newer C++ runtime the new exe needs; checked against every other DLL of 0.3.3.)
3. Remove BB_GPU_MERGE=0 if you set it.

To undo, restore the two files.

Please report in the issues

• U2: train wreck, a few loads from a fresh start.
• U3: London bar fight on 1.02 without BB_GPU_MERGE=0.
• U3 Cartagena square with BB_FRAME_STATS=1 (launcher "Environment" field), to compare performance with 0.3.3.
• Attach user\last_run.log either way.

Checked here: builds, guest-io-test passes, and bb-probe.exe --vulkan-only runs with the 0.3.3 DLLs. Not yet tested in the game itself.
