8600m GT Framerate Issues

Hello,

I'm currently using a Dell XPS M1530 with XP. When I enable Anti-Aliasing, my framerate gets a strange behavior; its stays normal for a few seconds then drops to about 10. I get those problems only with AA enabled, and they seem to happen with Flight Simulator 2004, Live for Speed and Pro Evolution Soccer 2008. I've tried three different drivers including the officials ones and two from laptopvideo2go.

Thanks

 

that sounds like your notebook is overheating a the videocard is downclocking when it hits a danger temp (hopefully you monitor your GPU temps).... then it cools down enough to run at normal speed again.

First, you need to make sure your vents are not clogged with dust (you are supposed to flush them out with compressed air every two month).

You need to make sure you are NOT blocking the vents and make sure you are using it on a hard, clean, flat surface (preferably a good notebook cooler, like Zalman ZM-NC1000 / NC2000)

 

If you are overheating... usually any temp over 90C degrees is bad.

when was the last time that you cleaned out the fans and vents thoroughly...?

if never, then thats why.

1) remove battery
2) remove/unscrew the panels on the bottom of the notebook to get to fans and vents (if possible)
3) use flashlight to look through vents for the dust (if you cant see the light on the other end, then the vents are clogged up)
4) go outside, get some compressed air (cans or compressor @ 50 PSI) and give the vents a good airing out all directions ( concentrating on the vents)
.... you might want to brace the fan blade(s) when airing it out (with a toothpick or paperclip to prevent it from spinning out too much)
.... or use short bursts (1-2 secs) of air instead of bracing the fans.
5) go get some Q-tips and swab the fan blades and the area around it
6) then go do a second airing with compressed air (all directions again focusing on the fans and vents) to push out the dust that was dislodged from the Q-tips

7*) Now go use the flashlight again and look through the vents (shine the flashlight from the fan, you look through the other end) for anymore dust clogs.

8) Then start up the notebook... and let the fans cycle up (use the Fan Toggle at max speed if your system has it) to push out any other dust that might have been stuck.

If all goes well you should be able to close up the notebook and...

you're done.

*repeat this step until its cleaned out.

Thats pretty much it.

Just make sure to do this every two-three months... it should take about 15-20min per cleaning if you want to be thorough.

Gaming notebooks are a new thing, you must realize that you have to take some extra care of them over typical use notebooks:

1) Battery: to maintain the longevity of any rechargeable battery
- you must NEVER overcharge it [especially for long durations of time] by keeping it plugged into AC
- when it reaches 100% you should unplug it and let it discharge to 5-15%, then plug it back to power
- OR you can just charge it to 50%+ and remove the battery and store in cool place.. not the fridge [remember to use it occasionally 3-4 time a year to charge and discharge it].

2.) Heat: to prevent a healthy notebook from overheating
- ALWAYS use the notebook on a clean, hard & flat surface
- RECOMMENDED to be used on a notebook cooler... namely the Zalman ZM-NC1000 or ZM-NC2000
- check your fans underneath occasionally (at least once a month or two) for any dust clogs [clean them out with Q-tips and air cans/compressors]
- ALWAYS monitor the temps (CPU, GPU, HDD, etc..) to watch for fluctuations, which would indicate overheating by dust usually
(for Clevo notebooks) use the Fan Toggle to switch all fans to Max Speed when gaming and such.

By doing these simple things, your entire system will easily last for more than 3 years.

 

I don't think that's my problem. It only happens when AA is enabled. Finaly, the FPS only last for a few seconds and then comes back to normal. It happens in a cycle...

 

what are your temps during those moments.... because I have experienced that before... it was overheating (hitting a temp around 95C) then it downclocked my videocard.... and came back to normal.

Use RivaTuner to monitor your GPU temps in-game.

 

I have that problem too. I don't think it's your hardware at all, it's the forceware drivers. If you read the release notes from Nvidia it states that AA isn't fully supported I tried 174.xx and now I'm on 175.19, so it taxes the gpu. I just turn it off altogether. What forceware drivers are you using? And read the release notes for that certain version on nvidia's site and I'm pretty sure it'll say that there are issues with AA.

 

Found the problem.. now need the solution.
What seems to be happening is that the SpeedStep is kicking in during the game. For example, the game runs runs and SpeedStep sets the CPU at 2.2GHz then randomly sets the CPU back at 1.5 at intervals. All I need to know is how to keep the clock-speed at 2.2Ghz. The option in the bios sets it at 1.2 when SpeedStep is Disabled...

My temperatures seem good
~60-62 CPU
~70-75 GPU

 

Downlaod Notebook hardware Control and set it for maximal performance, so it doesnt speedstep down .

Worked really well brainer.. gave you a rep point
