Great topic. On the shader cache side, the practical sweet spot for most competitive setups sits around 10–15GB in the registry (LocalSystem\MSSCachingV2), and honestly past ~24GB you’re leaving money on the table with zero real-world benefit—modern engines like Unreal 5 and Frostbite pre-bake so much that the cache just becomes a big LRU that thrashes. What actually matters for 1% lows is consistency, not raw size: a 12GB cache that stays warm across your session beats a 24GB one that constantly evicts because you’re juggling 6+ games. One thing people overlook is that the cache lives on your system drive, so if it’s on a nearly-full or DRAM-cache-depleted QLC drive, you’ll see the opposite effect—more shader compilation stalls, not fewer. If you’re chasing frame-time consistency, I’d pin the cache to a Gen4 with good
