Poor graphics subsystem performance

[iam-alex]

I experience bad performance of videocard (Haiku treats it as Radeon HD 5450 Cedar). Speed of some graphical operations (for exampe, selecting of an item in any menu) is extremely low. Haiku3D demo runs more slowly than even in my old low performance laptop. GLTeapot runs with hundrets FPS though. Lowering of resolution doesn't help. Also I have 2 monitors if it is important.

Try disabling ACPI.

I can not say it helps.

Does it become better if using failsafe graphics?

UEFI mode or BIOS?

[iam-alex]

I run Haiku with disabled ACPI and failsafed graphics in 800x600. Not sure, if it is faster, but, unfortunally, problem remains: Haiku3d runs with freezes. I found that Haiku3d runs fluently if I continually drag mouse. Trick doesn't work with menus, though.

PC runs under BIOS. Syslog made in half year old haiku revision, but now it is tested in latest Haiku.

In that case, please try blacklisting the "cpuidle" kernel add-on.

Yes, with blacklisted "cpuidle" it finally works. Thank you!
