I have a HP Pavilion dv7-2185dx, and let me start out by saying that this thing is freakin awsome. I only encountered one problem, and i can't find it on the web anywhere. When searching for frame rate stutters, i only found it mentioned on SLI or Crossfire cards.

When playing any games (I tried it on Team Fortress 2, Half Life 2 , episode 1,2, Conter Strike: Source, and Unreal tournament 2004 [which i believe runs on a different engine, so that rules engine incompatibility out) they all have excelent fps, but they all have sudden stutters. For a fraction of a second the fram rate drops into like the 5-10 zone. even when i put all settings low and get 120, 130 fps this happpens (and if i noticed it right, it happened on low in tf2, more than on high). And on high i usually get no less than 70 fps (but also with the drops to 5). I have downloaded the newest graphic drivers from the hp website. And this is an out of the box laptop. The only things i did where make a system recovery disk and install/run the game. It is less than a week old. I have included all the information found under dxdiag, under the sytem tab and under graphics.

It might be when the game has to hit the hard drive.
Laptop hardrives are painfully slowwwwwwwwww.
Or it could be that the processor is entering into a little bit of a powersaving mode, then suddenly something happens in the game that needs it to go to full power. Don't care what anyone says, this will cause some lag as well.
Laptops and gaming, no matter how you look at it, you are going to sacrifice somewhere. I don't care how they promote them, or advertise them, they just ain't made for gaming.

The hard drive is what i originally thought. But then i looked at the hard drive indicator, it stays lit at full during loading, and during the game just lights up every few moments. The cpu is a pluasible explanation but the stutters happen sometimes in less than 1 minute intervals; also i have the power managment set on high performance, so it shouldnt be going into powersave mode that fast. And i played the game on much worse laptops (20 fps) and there was no stutter at all. this problem would be understandable on a laptop with 20 fps, but 120 with dips below 5, i do not understand that.

I have a HP DV7 2140 eg (Quad, 4 gig, HD4650, Windows Vista 64 Bit).

And I have exactly the same problems as you. The only solution seems to limit the fps to a lower rate. But this isn't exactly a good solution.

What I tried so far with no success:

- installed the newest catalyst (9.9)
- configured Windows Vista Power Management to "Höchstleistung" (maximal performance)
- deactivated Windows Aero (Windows 2000 GUI)


I did a few tests and found out that the GPU / GPU RAM Frequency during the "choppy" games was at max (550 / 666) all the time so no special annomalities here. Even the CPU Frequency was exactly the same.

I think that there is something wrong with HPs standard-configuration (there is only a image instead of an orginal-Windows CD so you can't make a "clean" install). I hope that those problems go away when they send me the Windows 7 CD (from their Windows 7 Upgrade Program).

p.s. and no - it's not the hard disk...

Check to see if there's a BIOS update, maybe hit up the latest Intel Chipset drivers.

No Bios Update available and the Chipset-Driver from Intel is the latest :(

i returned the laptop, said that the graphics card was shot. got a new one completely the same and theres no more stutters (or so little that i can't notice them). Even the hl2 lost coast vidoe stress test doesnt get choppy (it did before). So i dont know was it the laptop or was it some setting on the laptop.

Well, in Half-Life 2 LC (and other Half-Life 2 parts) I don't have those problems - perhaps mine is something different.

I told the HP-Support and we come to the conclusion that I report back when I install Windows 7 (I think it's a misconfigured system).

I have an hp dv6 and a few source engine games also stutter for me (not all though). I was hoping that the windows 7 upgrade would help but it didn't. I did the upgrade not the clean install. Do you still have your problems? If you have managed to fix them it would be great to hear from you.

Thanks.

An upgrade install improved the situation for me but didn't solve it to a full extend.

I think a clean install is neccessary to get rid of stuttering because the images HP delivers don't just have the drivers required for your configuration - they have drivers for all configurations of their laptops - so they have unneccessary drivers included.

This console command fixed stuttering in cs source and tf2 for me.

Hope it helps
