"I'm on Linux, Asus Strix GTX970, i7-920, 8GB RAM, fantastic performance boost with 1.4 beta, much better than previous one, i can now easily see 60fps on most of the places, still some hiccups here and there but much better!"
"Windows 8.1,Radeon HD 5800, Intel(R) Core(TM) i7 CPU 860 @ 2.80GHz, 6GB RAM...same here, much better performance..now gimme the hardmode and everything is fine ;D"
"Wow. I am amazed. From unplayable 10-15 FPS to realy good 35-45 FPS. Still not Perfect, but a beginning!"
