Speed Steping Games on P-M

I own an Acer 292LCi which have 1.5gz P-M, 64mb ATI MR 9700.

If I select the power scheme in the Laptop as Portable/Laptop (which means dynamic CPU speed switching based on CPU Load) the speed of some of the games also increases as the speed of the CPU increases. For eg. when I start a game the CPU speed is 600 mhz but as the game loads the CPU speed increase to 1500mhz and the game starts running faster. (faster firing, running etc.) The games I found affected most were the orignal Unreal, Unreal RtnP, Splinter Cell and even Halo.

The only workaround for the above problems seems to be setting the CPU to a fixed value which can be done by either selecting Maximum Battery (CPU will run at 600mhz fixed) or selecting Maximum Performance (CPU will run at 1500mhz fixed) before running games.

I think this could be a problem with the P-M CPU and thus not applicable to Acer systems only.

Anyone who have any idea how this can be solved while in the Portable/Laptop power setting.

yea i encountered this problem with my friend's computer as well. i think the problem with p4m processors is that their main objective is extended battery life aside from wireless (centrino technobabble), so that is why the processor limits the speed or controls its speed very stringently. for example, have you ever tried unplugging your computer from the power supply and then booting it up, you'll realize that no matter what you do, you can never reach maximum speed? but in respect to your gaming question, this applies to my p4 w/ht too, when i put my option under portable/laptop my games are choppy, so whenever i play any games, i switch my power option to always on, and my gameplay is smoother, although how much smoother can it be on an fx5200? well hope that helps.

i use speedswitch to control my dothan processor
but when i play games they sometimes lag a little on dynamic switching to see if speedswitch can slow down the cpu that's why before playing i set the program to max performance and that makes everything run smoother.

My problem does not relate to choppy game play because of changing CPU speed while playing the game because in my case while playeing a game it dosen't go down from the highest speed of 1500mhz. So once the game gets started the CPU keeps running at maximum performance. The problem lies in the initial switch from 600 mhz to 1500 mhz and that actually increase the game speed (NOT FPS).
