Hi fellow users. Before i start, i'd like to say that i'm not very good at computers, so i may not know or understand some computer terms.

Here are my specs:
CPU: intel core i7-3517U @ 1.9ghz (4 CPUs), ~2.4ghz
GPU: Nvidia geforce gt 635m 2gb
8gbs of ram.

I've been having gaming issues lately concerning the fps. I play dota 2 quite a lot, yet i can't run it without having these stuttering lags. It would be smooth for a few seconds or a few minutes, then the fps would drop up and down which is very very annoying. I thought i set my graphic settings too high but the mini lags persist even at the lowest settings. I also tried to search for how nvidia gt 635m performs on dota 2 via youtube and i find that people actually play the game smoothly on high settings.

So i tried doing a couple of tests using GPU-Z and i found that my gpu load is only at 40-50% which i guess is very low. the temperature is ~80 degrees and the clock is somewhere at 600mhz. I have also updated my nvidia to the latest version (320.49) but it still lags.

I checked my cpu usage via task manager and surprisingly its only 20-30% while running dota 2. Is that normal? i don't think its a cpu bottleneck problem because my processor is decent.

So is there any way of increasing my gpu usage? thanks for your help.
