Graphic performance slow downs.

Let`s say that I start playing some FPS MW2 for example. Everything is ok at the start, it is smooth and ok but suddenly after a few minutes i see some slow downs and fps drop downs. Is is due to temps?

 

Which model system are you using and what specs? We need some information to try and help.

The other thing is since you suspect temperature issues have you monitored them and if so what are you seeing?

Edit; If we go by your public profile, P7805 & x9100, do you also use the stock power brick and where are you overclocked if at all?

 

7805u
9800gts
700/1770/890
1.14 core voltage
x9100

 

Are you using the stock 90w brick? if so this could be an issue where you need to lower the OC of the Video card. Also check your temps too as this can be an issue as well............

 

Delta Electronics
Output 19V = 6.32A
Input 100-240V
Model ADP-120ZB BB

 

120w output, better than the stock 90w but I am not too familiar. I would still check out the temps with hardware monitor and if they look fine as you game then try stock clocking everything. once those are eliminated you may need to look at driver versions etc etc etc.........

 

Mine is also the 120W, it was the standard part for the 78XX laptops as far as I am aware. And yes, it is most definitely being overdrawn in terms of power. TANWare just helped me figure that out in my thread

My recommendation is this - avoid overclocking for now. But there is a bit of a telltale sign to look for to check if your power supply is damaged/broken/close to death - See if your computer begins draining the battery when under heavy load. Play CoD single player and play at normal speeds (no OC) but also play at the normal voltage. Play through the moments where it slows down. After an hour or two, if you have used up any of that battery, then your power supply is not going to cut it. If you have to order a new one anyways, might as well order the 180W one. If yours is fine, then it's just a personal preference. I don't think I'll be getting the 180W for a little bit until I can see what the limits are of this current setup. If you really do want to push it to the limit though, then don;t forget to clean out the vents and fans with compressed air so that they can breathe. If here is a temp issue, this is a very likely culprit.

 

That happened to me all the time because of temps. Keep them low- there is a point when the comp. will reduce max gpu performance to protect you from frying it. I cleaned the vents and propped it up on three dvd cases instead of two and it helped.

Also, I would have to restart the computer to get max performance back.

 

His issue very well could be temps. I would think though if he thought this might be it from the original post he'd have posted so.It would be nice if he monitored and posted the results but the OP hasn't yet.

since he clocks GPU at 700 the shaders should be x2.5 or 1750, so he could lower that a bit. It could be too the video card can no longer be OC'd stable at his old settings. There are many things that it could be but the OP is not very forthcoming..................

 

"since he clocks GPU at 700 the shaders should be x2.5 or 1750" was the trick
i had shaders at 1770 and core at 700. so i lowered shader value and it all happened. seems to work fine. thanks TANware.
