So this is my setup: Motherboard: Gigabyte GA-M68MT-S2 CPU: AMD FX-4100 GPU: AMD Radeon R9 270 RAM: 2 sticks of DDR3 4GB HDD: WD Blue 1 TB Desktop Hard Drive PSU: XTREME GEAR 600W ATX I usually try to enjoy Altis Life on Asylum servers, but if I don't have chrome open the best I can get in towns is ~10 fps. With chrome open it usually drops to 3-7 fps. This is with everything as low as possible and very small view distances. I heard Intel CPUs do a better job with Arma3, so what should I look into getting for a cheapish price since I'd also have to buy a compatible mobo? Just having consistent 20FPS would be fine for me.
