Dedicated Simulation Thread

The simulation now runs on its own thread, freeing the renderer from heavy lifting. This boosts performance, especially in rollback-heavy co-op sessions or FPS-hungry builds. The renderer reads from a double-buffered simulation state and uses client-side prediction for smooth movement. This should yield better performance, smoother co-op, and an overall more responsive game.
A new Sim-FPS stat now appears next to your FPS. If it drops below 50 and turns red, the game will slow down to let the simulation catch up. This will feel like bullet-time, but should at least still be playable.
Co-op player info
When playing co-op, the game will now show some info about your co-op partner next to your buffs.

Bugfixes
Fix attack speed per time to also apply to Minions
Fix preview calculation of Instant Leech
Fix the cap of Leech in-game. The preview calculated this correctly, but in-game the cap was 50 times higher due to a technical error. The base leech cap has been raised from 10% to 25%.
Fix display of more damage affix quality range on Empowered Chips
Fix a rare stats glitch when hovering item allocated skills
