Compiled binary is provided for convenience as well as the source. A sample application is attached which attempts to isolate the problem. The core of the problem is that when a texture is created with immutable storage, pixel transfer operations with endianness swap will always fail with GL_OUT_OF_MEMORY.
I have tested this on several AMD cards from the 7000 series to the RX 480 and 580. I have encountered a rather interesting bug with pixel transfer operations. Here's the discussion for those interested: ĭiscussion transcription for those who can't open the link: Please update your driver to Adrenalin 19.4.3 or newer.
This fix first shipped on AMD drivers 19.4.3, so you should update your drivers to at least that version if you intend to use RPCS3 with OpenGL and you have an AMD GPU.įor those who don't get to see this piece of information, RPCS3 should throw a fatal error if this bug is hit on older drivers and tell users Memory transfer failure (AMD bug). This bug impacted RPCS3's performance on AMD GPUs while using OpenGL because pixel transfer operations with endianness swap on the GPU always failed on the affected drivers, so we had to manually byteswap texel data on the CPU. AMD just finally fixed one of the driver bugs u/kd-11 (our lead graphics developer) reported to them exactly 1 year ago.
