Unfortunately I have to report a bug.

Since I installed the kernel I get extreme screen flickering with certain games. "Tyrian" is one of them.

I think that the system is switching between gpu and cpu rendering constantly. I use the default governor and scheduler.

In every other aspect this is a phenomenal kernel.

Please, give me some time and I will test it.
It will be helpful, If u know how, make a logcat and/or dmesg while you're opening the game and attach the logs here...

Yes! It disables 2nd core when phone is idle (also when the cpu usage is low, although the screen is on)
For check, use some tool like Kernel Tweaker to check the state of each core
Interactive governor is more responsive, also it scales to max frequency more than Abyssplug. Probably, interactive gives more performance and responsiveness but isn't too battery friendly like abyssplug is (abyssplug is based on hotplug, which is based on ondemand).
If you want more details, you can check this link

none problem
I will try to test it myself, but your logs can be very helpful.
BTW, is your CPU overclocked? What is your max freq?

No overclock, max freq is 1Ghz.

I have attached the logcat and dmesg of a freshly booted system (I also ran the affected flickering games). I hope I did them right because logcat is huge...

(Also, PAC perfomance, after I have replaced my default kernel with fude, force closes in the cpu tab. This not important to me since I use "no frills cpu" but I hope it will help debugging.)

Man, again, your kernel is the best I have seen. Thanks for sharing it.

I've analyzed your logs and there's nothing unusual... I tried "Open Tyrian" with 1.4.1 and 1.5.1 and performance is the same
None flickering there... I noticed you have swap or zram, maybe you can try disabling it... To do it, remove scripts from /system/etc/init.d.
Tyrian works fine but without OC, with OC, my device reboots.
Please, can you tell me which other games have you tested?
