The main concern of a PC Gamer is to get the best performance out of its PC. What settings he/she must adjust to get the best playing experience. Calculating the in game fps can help a, PC Gamer, lot. There are many tools over the Internet but I like the FRAPS as the best benchmarking tool. Using FRAPS one can calculate its in game fps, capture screenshots, and also can capture realtime videos of one's gameplay.
