[x] Fix remaining regressions after optimization changes (Nier) - https://github.com/RPCS3/rpcs3/pull/12169
[x] Accelerate CopyImageToBuffer and CopyBufferToImage to improve typeless copy performance.
[x] Refactor GLHelpers into something more manageable
[x] Accelerate BGRA<->RGBA operations
[ ] SPIRV shader compiler
[x] Implement proper async shader compilation using the extension (Cancelled, not feasible)
[x] Port FSR to work with GL
[ ] MSAA support

kd-11 commented 2 years ago

Optimizations are mostly complete, but I need to avoid doing full buffer round-trips for some data types when doing copies. These can be trivially implemented using custom shaders. Specifically BGRA<->RGBA conversions need not use the slow copy method with double compute pipelines. After that I only need to do async shader compilation and FSR to get OGL to have functional parity with Vulkan.
