@Daytona675x

Try setting the unused arrays to UINT8 as well. That should work for now, until I add a proper option to disable endianness conversion.

Anyway we just need a new VBO mode (let it call W3DN_RAW_ACCESS) that dont copy GPU vram to/from a reordered buffer but only let it accesses the VBO data at their place in the GPU vram (so it is the cpu that will manage the reordering & copy)

That would be a workaround for the lack of GART/DMA. We really want to move away from the CPU accessing VRAM directly, because it's really slow.

At some point we'll finally have GART support, which will allow us to use DMA to copy data to/from VRAM, and even allow the GPU to slurp data directly from RAM.
