I just bought new computer last week.
This is my computer information:
Operating System: Windows 8 Pro 64-bit;
Intel Core i5 4570 CPU 3.20GHz (4 CPUs) ~ 3.2 GHz
Memory: 4GB RAM, page file 12 GB
Display: Graphic card AMD Radeon HD 7700 Series. Approx Total Memory: 2765 MB
Today I playing Leauge of Legend only (I didn't open any other tab or program) but still my FPS when so low (about 30~ 40). I think is impossible with my graphic card and CPU. Can somebody help me how to raise my FPS to play better?
