Thanks for the explanation. Is "scaling parameters" something I can alter with setcpu? I have it install, but I have it set to just 998 and 245 ondemnod. I fear overclocking will break my cpu.

I've noticed that on gears, it's a little erratic, it fluctuates between 43-49, which makes it look a little choppy. I think it looked a little more smooth when it was consistently at 31fps.

Is that why, the first time around when I run fps2d it works its way up to aboue 54-55 and the sd is larger, while immediately running it a second time, performance is more consistent?

3.7.3c and OMJ 1.7 here. I keep getting hard crashes on gps activation.

Yes you can, if you go to the advanced tab in setcpu you can change the governor parameters. The 2 you're mainly interested in are sampling rate and threshold.
Sampling rate is how often the governor checks the cpu load to decide if it needs to increase the cpu speed, I personally use 50,000 (about .05 seconds).
Threshold is what % of cpu needs to be hitting before the governor starts increasing the cpu speed, I prefer around 70 to preserve that snappy feeling. Setting it lower can improve performance, but can increase battery drain.

Gears can be a touch misleading to the governor since it doesn't hit the cpu as hard as fps2d might. Generally I tend to advise people to fire up setcpu (or whatever clock control util they prefer) and set the governor to performance for the benchmark to see what your peak is. (Just remember to change it back to ondemand when you're done ofc!)

That's exactly why.

When you first fire up fps2d, you're probably still running at min, and on that first run the governor will be ramping up the cpu speed to meet the load it's seeing from fps2d.

On the second pass, the speed is already scaled up a bit(unless you let fps2d idle long enough for the governor to scale the speed back down) so there isn't as much fluctuation.

Hrmm, this may be rom specific, I've been unable to reproduce any crashing.

How are you enabling gps?
Through the menu?
Through a widget toggle? (if so, which widget are you using?)

Well, I'm going ahead and updating to OMJ 1.9, I'll see if the problem persists.

I'm thinking something is the system may have become corrupted. It was crashing when the gps was being used by an app. It was already on, but when an app searched for a location it would crash. Turning gps off stopped the constant crashing. I'm still not sure what the actual cause was.

hey net what was causing the wi/fi and 4 g issues in the previous release i was running damage control 3.23 but was having a huge problem with either 4g not turning on or wi fi not turning on and my 3 g kept cutting out so i bounced back to finisher evolution remix which i think is based off baked snack rom.

It was a permissions issue that snuck in when I was editing the update script.

Someone please help me understand the benefit in flashing these kernel. What is the benefit in higher fps. What I'm looking for is a better way to send higher mms, better video encoding. Will these kernel allow this. Please help me understand how to use the faster fps.

Well, it's working great now. I think something got corrupted before.

Can underclocking cause data corruption? I recall sering someone mention that somewhere.

I'm not aware of any reports of underclocking causing data corruption.
Technically any speed under 998mhz could be considered underclocking. The phone by design scales the cpu speed as needed based on load, in order to save battery power.
