The previous FLIP_DISCARD swap chain configuration was producing broken rendering and a stretched aspect ratio on startup and after window resize, because the closed-source 4J Renderer library holds hidden backbuffer references that prevent ResizeBuffers from succeeding in flip mode. Switches the swap chain to the legacy bitblt DISCARD model with BufferCount=1, which lets the "destroy old, create new" resize path in ResizeD3D work cleanly. In-world rendering and aspect ratio are now correct at launch and across window resizes. Known regression from this change: screen tearing no longer works when VSync is off. On Windows 10 and 11, bitblt swap chains always go through the DWM compositor, which locks presentation to the monitor refresh rate regardless of the SyncInterval parameter we pass to Present. Every frame the renderer produces above the refresh rate is silently dropped by DWM, which hurts input latency compared to a true uncapped-fps presentation path. The next iteration will reverse-engineer the 4J Renderer struct layout to find where those hidden backbuffer references are stored, release them before ResizeBuffers, and switch back to FLIP_DISCARD with ALLOW_TEARING so real tearing is possible again. Also removes the dead SwapChainVSyncProxy COM wrapper. The proxy was originally intended to intercept Present calls from the Renderer library for VSync control, but the library hardcodes SyncInterval=1 and does not dispatch Present through the proxy vtable, so it was never actually doing anything useful. |
