* Vertex Buffer Alignment part 1 * Update CacheByRange * Add Stride Change compute shader, fix storage buffers in helpers * An AMD exclusive * Reword * Change rules - stride conversion when attrs misalign * Fix stupid mistake * Fix background pipeline compile * Improve a few things. * Fix some feedback * Address Feedback (the shader binary didn't change when i changed the source to use the subgroup size) * Fix bug where rewritten buffer would be disposed instantly.
