Someone mentioned that the dx11 beta may be forcing vsync to be enabled even if it's off in-game, which can add considerable delay if you're not used to it. Try forcing your drivers to disable vsync in Nvidia's control panel or AMD's alternative
No-Downstate makes the game boring. Landing good burst and watching players evaporate into a gray nameplate rather than dealing with downstates/rallies removes too much play and is unsatisfying. I'd rather see experiments with removing downstate's invulnerable tick or conditions persisting through transitions if anything is changed before no-downstate is ever considered.
