The replay thread deswizzled every block-linear texture on the CPU, and entering a new area stalled it for 50-236 ms. Now a compute pass reads the texture straight from the pool's imported buffer and writes a linear copy into a device-local scratch pool; the upload batch copies it into the image, or the ASTC decoder takes it. Large texture loads submit the batch early so the staging and scratch pools do not grow on the replay thread, and both pools are made at device creation. On fight2 the render thread waits about 270 ms on textures per run instead of 900, and the load frame drops from 145 to about 80 ms. Mean fps is unchanged. TOTK_DESWIZZLE=cpu turns it off and check compares every upload with the CPU result (0 of 196k regions differ). Shadow mode (Linux/Wine) and textures outside the device's limits stay on the CPU.
