A6-3410MX APU | int HD6520G | dis HD6470M , lost my switchable graphics

[Prime_m8]

I have a laptop (Samsung) with A6-3410MX APU | int HD6520G | dis HD6470M , lost my switchable graphics

i used to have vision control center and i could set high and low performance settings and GPU affinity basically per app or exe
and any exe set to high woudl make use of dual mode if on .

now it seems it is just off, but some how AMD is remembering the old affinity settings because the ones i have set before latest CCC , well they remember their settings even thought switchable menu rite now just dumps me to hydra vision .


the issue is this , i cant set it or unset it .

if i write a small d3d app , and the exe the name 100% the same as one of the apps that once were set to high power , both GPUs get used and well they run better .

if i recompile same source but to a new name , it runs all on one GPU only .

funnier still if i rename any exe that is working on both GPUs from what they were called back when i could set high or low performance , they run in low .

the new CCC i have tested loads , and i cant seem to revert .
im 2 whole days now removing drivers and trying to step-back .
and the old drivers that worked no longer install ?

Am i missing a thread or post.
I will try to scrape all the ATI out and do a 'clean' re- install again.


:::::

seconds after first posting this i found : AppData\Local\ATI\ACE\APL
in it is GpuAffinities.xml
and sure enough it has all the exe vs their GPU affinity settings

::: i just wish ATI did not pull switchable support from my APU & GPU combo.

I had a laptop with that specs too, and it seems after a certain catalyst driver, AMD "forgot" about the switchable graphics menu. I think AMD just stopped the support for Llano+VLIW graphics, sorry to say that but it's the truth. Why? I don't know. You can't switch between your graphics (besides OpenCL and OpenGL) anyway, but you can decide if Dual Graphics will be used or not so it's still a important setting.

yeah, i love this lap top .

i had until just a few days back when i was testing a beta of a friends game before V2 goes up to Steam, i could set weather a app was high power or low , and if rig was dual or not .

now if i name any exe to the name of one that had a profile , (profile i cant change ) the as such renamed exe runs with the old locked settings.
that seem to override dual mode global settings.


I even tested the express remove all option , full scrape,with exception of doing so in safe mode . LOL

I also notice all new catalyst drivers detect my HD6470M as HD7200 srs card?

>> it take so long to scrape and step back each version till i hit one that works .
i shoudl do a full scrape , and go back to OEM , file from Samsung . and then step forward as i find forward stepping to be easier. LOL .

:: i have used AMD at home since the first 586 PC came into my shop . I have had ATI video since VooDoo died .

if i do build my next rig AMD & ATI again , it will not be a APU , unless the built in GPU side is enough to do what i need for the few years of games and contract work.

>> using the new(er) beta drivers its all run smooth , just those pesky profiles.
if only i could find a way to edit them i would then have best of both worlds , because clearly some driver / settings some place is still at work .

hell i'll make a tool to edit the xml if i have to .
I have been crawling the UI xml to see if i can find a enable switchable menu target flag, but no luck yet .

i think i'll give this version a try

I have just done teh clean sweep and put the OEM , in but some things in W7 are expecting new display drivers.
