TODO LEARN this sht

• StructuredBuffer (shader)
• DrawIndexedInstancedIndirect
• Thread create and kill (could save a few ms) when changing area
• Port d3d9 math to DirectXMath
• Some hotspots on PCMPISTRI (https://stackoverflow.com/questions/58901232/why-is-sse4-2-cmpstr-slower-than-regular-code)
• Memory optimization (why this game eats alot of ram)
• Update all modules, change zlib to libdeflate/zlib-ng
• change to https://github.com/GPUOpen-Tools/compressonator with brlg for lower texture size.
• Move win32 UI to another thread to remove window ghosting.
• Change locks to Critical Section into SRW locks(?) (and if possible lock-free engine)
