#16292 closed bug (duplicate)

Poor graphics subsystem performance

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.

comment:2 by iam-alex, 10 months ago

I can not say it helps.

comment:3 by X512, 10 months ago

Does it become better if using failsafe graphics?

comment:4 by diver, 10 months ago

UEFI mode or BIOS?

comment:5 by iam-alex, 10 months ago

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.

comment:7 by iam-alex, 9 months ago

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