How do I fix shader compilation delays in Planetside: Aftermath on a Manli RTX 5080?

Loading screens were painfully long due to 5.2GB shader cache. Force-deleting the cache made it worse, triggering full recompiles. I used GamePP Shader Queue Manager to clean in stages. Compilation time dropped from 45s to 12s, and VRAM temperature stabilized at 62-66℃.
