CPU usage when touching screen

[mysticbluebmw]

Can anyone else confirm this problem. When I press the stylus to the screen abd hold it there momentarily, the CPU usage for gwes.exe jumps from about 0.5% to about 33%-35%. This causes major lag in stylus based games, and draws extra battery power in any application with heavy stylus usage. My old HP Ipaq hx4700 never had this problem, and since my Tytn was qvga, it would have been hard to tell if it did this or not (its gone now, so I can't test it)since it doesn't have to push the 4 times higher resolution of VGA.

It was bad enough, when I found out(I really did know something was up, though) I was saundering around at 100mhz to 312mhz nearly 100% of the time, due to the SUPER CONSERVATIVE built-in auto scaler. Now I feel like I got completely duped on my purchase of an advertised 624mhz cpu. My hx4700 blows the doors off the Advantage in terms of processor speed. They both have a 624mhz CPU!

If you don't have a CPU monitor there is a program in attachment. Install it, run in background and just press to the screen for more then 2 sec. and watch CPU utilization level.

Well, I never really find U1000 to be anything faster than any WM5 device I owned before. Even with my O2 IIs felt much snappier than U1000. It's an inherited problem with WM5 though since WM6 would make U1000 way a lot responsive.

you should never compare QVGA device to VGA device, the power needed for VGA is a lot higher, and if you use PHM, you can have CPU speed set to 728, and it will run a lot faster and smoother.

Hey Wu,

I tried to test 728 but my my U1000 froze. Yours were ok with 728Mhz specs?

This is a pretty serious problem. Does anyone else see the gwes.exe process jump in CPU usage from a reasonable 0.5% to a 33%-35% increase when holding the stylus to the screen? This makes using the stylus a intensive CPU hog. Being a touchscreen device, that should be a bad thing!:(

Could you imagine your home PC doing this every time you move or click the mouse?:confused:

Yes It happened to me as well. touching the screen does increase the CPU usage up to 40%.

How about using the supplied keyboard? Meaning when you press or hold the key?

yes, mine one works ok with 728, my machine is flying at the moment, just trying to figure out how much more battery cost this is.

I tryed it, and its not signifigant. Weird thing is letter keys only jump an extra few percent of CPU usage, while for me, the space bar jumps and extra 9%-10% of CPU usage.

I emailed HTC, and explained the problem on Friday, so I should probably hear back from them in the next couple of days. Though I'm sure it will be, I hope it's not a useless, canned response. I tried playing a couple of different games today (skyforce, meltdown). Both run fine until I touch the screen, and then frame rate drops to about 1/3 of the original rate.

I tried overclocking to 728mhz, and while it doesn't freeze up, it doesn't help the perceived speed of the Athena either. I can tell NO difference. Though, battery draw was about 2.5-3.0 times larger than when leaving it on it's built-in auto scaler. An hour of heavy usage brought me down from 100% to 60%, and again with no noticeable difference in speed. Way too unacceptable for me!

I have same behavior
CPU utilization jumps from 3% to 50% or 60% when pressing on the screen with the stylet. Now I understand why there is skiping in games that use the stylet. Did anyone reported this to HTC??

This has been a problem with most WM5+ HTC devices I've been reporting them for over a year, in several articles of mine.

It seems they still haven't even tried to fix it. :(

Can you pls post the adress you have used to report so I spam them a bit as well ;)

Im using WM6 and I have the problem ...
