Hi,
This question is probably fairly out of date but it's quite bizarre if you ask me. Let me preface my problem by saying that games run as expected for the most part; I'm not expecting insane performance out of this chipset because I understand that's not what I'm going to get. That being said, I do understand what to expect from this chipset.
Back when I first started using the laptop (light side gaming, I have a dedicated gaming machine) games ran pretty much flawlessly; 60fps, the perfect smoothness, no chopiness, etc. It's quite easy for me to tell when a game drops below a certain threshold, say, 55fps, because I'm so accustomed to playing with constant 60 on just about everything (yes, I'm a graphics snob).
Now, I played with perfect smoothness for a while, maybe a couple weeks, a couple months, don't exactly remember. Then one day, framerates just got noticeably worse. I would be fine with this if I had known what caused it, but there didn't seem to be any significant change to my computer that might have made this happen, and no changes were made to the in game graphics settings. And what's worse, the fps counter was not reflecting the changes in fps. It would still read around 55-60fps when performing easily below 40 constantly.
(For reference, when I first got the laptop I was into MMO gaming, I primarily played AION...now I play League of Legends and that's about it)
So I just went with it for a while, 40fps is far from "unplayable"...just a minor inconvenience. So now every couple months or so, the "perfect smoothness" of 60fps returns, and a few weeks later, it goes away, only to be replaced again by general choppy-ness and it's annoying. I've tried driver updates and a variety of other things, but no one seems to have this problem, and it's difficult to describe unless I give a very lengthy description of the issue.
TL;DR
Computer works fine for a while, then drops in performance for a few weeks, then works fine again. Framerates are low but the computer says they aren't.
I feel like this may not be a problem with my graphics card, please help. If you have had a similar problem and have found a solution or know what causes it I'd love to know
