Wow I'm having the same issue with my 7970. It does not stutter all the time but in games like far cry 3 it dips to 30 and bl2 even though the framerate is above 60 most of the time it still hitches. i7- 4670k, Asrock extreme 4, no overclock. Also my gpu idle temp has gone from 33 to to 36. Please help. Also whenever i try to run hwinfo 64 it crashes my pc when checking for ide.

The system does not blue screen it just looks as if it freezes (locks up, system becomes unresponsive) so I press the power button on the mobo, even result in a delay before the system restarts.
 
OK, so when does this happen? when you are in desktop or playing a game? does it happen all the time or is it random? Far cry 3 ran badly on both NV and AMD cards upon release , there has been patches but not sure if it is fixed yet.What is your Physx setting in Bl2?

On the desktop it's fine ( monitors color leaves something to be desired outside of gaming). Bl2 no physx gives me like 80 - 150 fps and dips to like 40 something if I should run up in the normal effects when their is alot of it at one time. The game is giving me smooth frame rates but I don't know if its a problem with vsync but sometimes when i turn it on and off it fixes the issue but if I should exit and return, it comes back albeit with the same frame rate with no lower than what I was getting when it was stuttering or not. Far Cry 3 i get like 60 fps with vysnc and then it drops to like 40 and has bad a stutter for a few seconds, same as metro last light but its stuttering I have only seen like 3 times so its a non issue. My gpu is idle at 38 degrees when it used to be 33 too.

What is your driver version? are you using the latest driver?

This is how vSync works. Your actual framerate is always going to be an even divisor of your monitor's frame rate. In other words, the frame rate is capped at 60 FPS, and if you drop down even 1 FPS below 60, you have to go all the way down to the next even divisor, 60 / 2 = 30 FPS. Drop down one FPS below 30 and you have to go down to 60 /3 = 20 FPS, etc.

The reason for this is that the frame rate has to sync to whole monitor refresh cycles. At 60 FPS you are doing 1 frame for every 1 monitor refresh. At 30 FPS, you are doing 1 frame for every 2 monitor refreshes. 59 FPS would be 1 frame for every 1.017 monitor refreshes, leading to tearing.

Generally speaking you should not enable vSync unless you know that you're capable of hitting over 60 FPS in all situations.

ok but without vysnc off my screen flickers, not really flickering per se but for lack of a better term ill use it.
 
Increase in temps could be due to hotter ambients (is hotter outside) -- I've even noticed slightly hotter idle and load temps on my gpu and CPU as it's been hotter than usu where I am. You could also try a good dusting. I wouldn't worry too much about HWInfo causing a crash -- try other progs like speccy, CPU-Z or Hwinfo (not 64).

If you're getting crashes during general use, then I'd be concerned.
 
Man I am quite dissatisfied with temperatures my pc is reaching when idle and under load. Currently all 4 i5 cores are hovering between 40 and 50 idle. GPU is 40.
Really need help because at load now its like at 68 for the cpu and 66 for the gpu and these are stock settings. Really need some advice as to where to go from here because I don't want my system to fail.

68C load is perfectly fine for a CPU and 66C GPU load is positively frosty. Most cards reach >80C when doing anything remotely stressful. Don't worry about the temps.

Is it tearing? As in, you see a horizontal line across the screen where the image seems to be slightly shifted?

Yea without vsync it does that mostly in far cry 3 (stutters too) but still shows up in other games too. The screen also has a wave like movement on it when playing games which is non existent when doing other stuff.

Temperature seems fine now but watch as soon as I start playing games its going to start to idle at 40+. But i guess its just the air temperature around, like you all have been saying.

For games that have wildly varying framerates like Far Cry 3, it can be difficult to get a good compromise between no tearing and avoiding the framerate penalty of vSync. You'll have to play with it and see what works best for you on a game-by-game basis.

ok thanks but do you know the cause of this? "The screen also has a wave like movement on it when playing games which is non existent when doing other stuff."

I'm not certain what you mean to be honest. Can you capture it in a picture or (more likely) video?

haha i knew that you probably wouldn't understand it that easily, but it looks more like shimmering and flickering which shows up in all games, even though its not all that noticeable. Also which program can i use to record it?

Anything that's a monitor issue won't show up when recorded via software. You'll have to use a good, old-fashioned camera.
