Origins suffers from a driver-related bug which causes the Z-buffer to become reset on the 3D character viewer. Bioware programmers forgot to check the error code when retrieving the Z-buffer pointer, and when this pointer is invalid, the attempt to dereference this pointer triggers a memory access violation.
I have altered the program to intercept attempts to access the Z-buffer. I inserted a new code segment into the executable, which is responsible for performing the missing error checking.
If this patch works, or if it does not work at all, please leave a comment listing known hardware and/or graphics driver information. Important data includes the operating system, the CPU architecture (32-bit or 64-bit), the video card or chipset, and the GPU driver version.
A text notice will be displayed at the top-left console area when a crash is prevented.
Digital Rights Management (DRM) software systems protecting the original game executable were not tampered with, or affected by, the changes I have made to the executable.
