So i have i5 3350p 8 ram 1600mhz kingston 1 tb hdd and gt 640 so i play on 1440x900 with low fps on very low only refleciton on normal and texture on high so its ugly and unplayeble so i optimizated the game in geforce exp still low fps then from nvidia conrtoll panel i chose high performance on everything and now exsept low fps i have lag... why? First of all i think the ram is enough the cpu not sure if you guys can tell me and second the gpu isn't that good but i though it will get at least 40 fps so why i have lag and lwo fps/ is it a virus?
