I'm afraid that my system is not using graphics card the way it should (thanks to God [or, devs] it's used at all).
How to fix issues listed below?
1) GPU core clock always at the bottom (stepping: shouldn't MHz go higher when 100% load?) and
2) GPU load is jumping from 0 to 100%, highly rare between (shouldn't it be 50% instead of 100% and 0 %? And why it reaches 100% while the only 'working' app is the terminal?), both 1) and 2) not depending on doing nothing (terminal actually) or playing
Flash Chrome video. Only difference is CPU (notice C) load 50% for Totem and ~100% for 144p Flash (so youtube-dl does great job instead
user@machine:~$ aticonfig --adapter=0 --od-getclocks Adapter 0 - AMD Radeon HD 7340 Graphics Core (MHz) Memory (MHz) Current Clocks : 283 667 Current Peak : 523 667 Configurable Peak Range : [283-523] [667-667] GPU load : 100% user@machine:~$ aticonfig --adapter=0 --od-getclocks Adapter 0 - AMD Radeon HD 7340 Graphics Core (MHz) Memory (MHz) Current Clocks : 283 667 Current Peak : 523 667 Configurable Peak Range : [283-523] [667-667] GPU load : 0%
I'd just add that
aticonfig overclocking appeared not supported by this card and I've changed Totem (
gstreamer) video plugin for
X Windows System which presumably lowered CPU usage for higher GPU load.
3) Flash player dropping frames as shown below img 8KB (I'd prefer 100% GPU load for 100% of time instead dropped frames) and
4) I've managed to get accelerated rendering in
Flash, yet couldn't make it to accelerate decoding so far.
chrome://gpu/ shows everything green & accelerated and no problems detected... so I take it as cruel to doesn't accelerate video decoding. I've modified flags for
Compositing: Hardware accelerated on all pages and threaded, no difference from default noticeable.
Tried to update
Peeper but it makes not difference since I had up-to-date versions. Tried disabling Pepper, but that disables accelerated rendering as well and makes Flash video black-blinking, it does nothing good at all. And yes, I've enabled HTML5 videos but it doesn't always work and even doesn't make much of a difference (dropped frames are not listed  but still noticeable [lol]).
Short notebook spec:
AMD E2-1800 APU (Accelerated Processor): strange enough it is 1700 MHz and 850 MHz from System Profiler while as far as I know it should be 2x 1700 or 2x 850.
4GB RAM & 4GB swap file
AMD Radeon HD 7340: 283 MHz x 667 MHz for 384 MB
Run by Catalyst 13.12 x64 not beta (drivers & control center by AMD for AMD on Linux) under Ubuntu 12.04 Precise x64.
Respect for going through all this text. Any idea?
Catalyst 13.12 I was using 'recommended'
additional drivers (tried bunch of them), but after a while I stayed with Catalyst.
For Mozilla Firefox I don't have even Flash accelerated video rendering (while enabled ofc).
