Hi. I am currently running the game on my i5 2500k, GTX 660 8 GB ram machine and I've been considering upgrading to Windows 8.1 for a while now. What I am wondering is if anyone have any experience with Planetside 2 running on the same machine but with Win 7 and then 8/8.1. I've heard games like Battlefield 4 can gain a lot of FPS in Win 8/8.1 compared to 7. It would be fun to know if anyone's gotten a big buff to FPS or performance in general.
