AMD Athlon Silver 3050U, 4GB RAM. hrev57937+118

Using WebPositive,

CPU goes 50% when scrolling haiku community forums and CPU idling up to 20%, Memory shootsup to 1.3GB.

Beta5 still lacks graphics acceleration. There is a prototype that is slowly being worked on for a Radeon HD series card but it is not in the Beta branch.

Thanks, Is there a list of supported graphics cards ?.

I’m just providing feedback.

There are no supported graphics cards for 3d acceleration.

Haiku’s main feature / attraction / charm is lost when applications hog cpu and memory.

Linux Mint Mate 21.2 have better optimization on the same hardware with firefox playing full screen video.

6

It’s not about optimisation, it’s about hardware accelerated video playback/decoding.

7

Hardware acceleration is not needed for video playback and decoding. You can play video in Media Player perfectly fine without acceleration on most hardware.

It’s definitely about optimisation, a lot can be done just on the CPU.

Is this in general or just for Haiku ?.

Linux Mint Mate 21.2 - FireFox, CPU is lessthan 10% and memory is about 1.3GB when playing 720p videos.

If it works in Haiku, it can work in other operating systems too :slight_smile:

Funnily enough, a ported app, qmplay2 can often play back videos with a higer frame rate/less cpu utilization than MediaPlayer. So we have room to optimize aswell.

Accelerated video decoding is nice to save on battery in a laptop however.

I cant replicate this, with youtube (Falkon) running video(360p) in the background, using webpositive to browse this forum, when I scroll I never see more than 35-40%, and this system is really old (AMD FX based, “8 core” Opteron, DDR3 1333mhz) from ca. 2010.
So with 2 browsers running simultanously I am nowhere near 50% CPU

What are your system specs for this scenario?
