hey, i was playing bioshock infinite and at this point i had been playing for a little more than an hour, and i was starting to get little bits of micro stuttering and sometimes hefty lag. but when i first start playing the game it runs perfectly fine like 50-60 frames. i was just wondering what would cause this problem and possibly how to fix it?
 
Solution
How about a little info as to the specs of the system you are playing on... and the resolution you are playing at.
Processor, gfx card, memory, MB, PSU make/model, age of system...
