Check your temps, it's probably thermal throttling because it's baking inside.

 

it says my cores are at 63.4C is that high if so what should i do to solve this problem

 

63.4 at idle or during gaming? I would get some temps while gaming. 63 at idle sounds a little high but nothing I haven't seen before. Run *this* program, and after you run into the massive FPS drop, press alt+tab to get to this program to see what your under load temperatures.

 

my temp while gaming is 71.0C Also my max memory was 41mb is that low for the memory?

 

hmm.. 71c is most definitely not a thermal throttling temp. The next thing I'd try is updating the graphics drivers.

 

does my memory have anything to do with it it ays im using 41 mb shouldnt it be higher?

 

Well, it depends. It seems with what I can see through a quick Google search, that Gunz is an Online Client based TPS, and in that case 41MB would sound fine to me. Now on games like Borderlands and Bioshock and WoW that have large amounts of data on the HDD they would use more memory.

 

so what else should i do to improve my fps any settings i couldve changed by mistake to lower them

 

Is the game Adobe Flash based? Or does it have it's own client? If it's flash based maybe a Flash update? Reguarding settings, I don't really know much about that game, but I'm sure you can try posting about this in the Gaming section... *here*. Those guys will be able to help you out more than I can.
