Severe Performance Issues on Breach + Delirium Maps

Hi everyone,

I really enjoy PoE2, but I've been running into serious performance issues on Breach + Delirium maps. Despite my high-end system (Intel i9-13900, GTX 4070 Ti, 32GB DDR5 6400, and a 2 Gbps optic fiber connection), the game lags, stutters, and registers input delays when I'm swarmed by magic monsters. This drop in performance makes it nearly impossible to survive—forcing me to choose between un-juiced maps that are too easy or hyper juiced maps where lag and stuttering cause unavoidable deaths.

Has anyone encountered similar issues or found any settings/workarounds that might alleviate the problem?

Thanks in advance for your insights!
