Now we have 5 (five!) Catalyst versions (11.5 -11.9) with this bad 100% CPU load bug. It was not there in 11.4.
Does AMD not care about it's customers?
This bug affects ALL of us!
I am seriously pi**ed!!

In 11.9, It is fixed for windows and Linux fix will be available in future releases.

No, it's not fixed.
As I already wrote for the 11.9 RC driver, for system with more than one GPU the bug still exists!
I have a system with 2 x 6970 - and I get 100% CPU load per CPU. With Catalyst 11.9
Question: Do you not test your software at AMD before you release it????
I don't experience any performance degradation with 11.9 (in comparison with 11.8). CPU Load is about 15% for 4-core CPU.

No, CPU is used only for feeding data to the GPU (data copying is overlapped with kernels running).

Originally posted by: Raistmer genaganna, did you read my report? It "fixed" at the cost of unacceptable poor performance. In fact, Cat 11.9 just as unusable in high-performance computations as 11.8. For my own GPU (HD6950) I see degradation on all Catalyst drivers after 11.2 ! It's much more than just 5 releases....
Could you please give a test case to reproduce this performance difference?
Are you using SDK2.5 for both drivers(11.9 and 11.2)?

Originally posted by: Raistmer Originally posted by: genagannaI can provide benchmark, but to see that difference you need to busy CPU with some tasks too. Those tasks can be idle priority ones (so, driver/runtime "should" get all CPU it needs...). App was compiled on another host (actually it's netbook w/o compatible GPU at all. APP SDK 2.5 was used at compile time). CL file provided in text form, no precompiled kernels. Thn app's exe + cl file used on another host under Vista x86 + Cat11.2 and Win7x64 Cat 11.9 Guru3D. So, all app kernels were recompiled under corresponding Catalyst drivers. And pp executable was linked against APP SDK 2.5 (in both cases).Originally posted by: Raistmer genaganna, did you read my report? It "fixed" at the cost of unacceptable poor performance.

Please give us benchmark.

When members of the AMD team write "Please give us more info" it usually means: "We don't care about your s**t - but at least we give you the impression that we would."
It certainly doesn't help when people claim "it is fixed".
Really because every single MULTIPLE-GPU system I have tested the 100% cpu bug remains.
Did a clean install of Windows 7 on machine w/ 2x 5970s, installed Catalyst, installed SDK, ran examples in SDK .... drumroll ... 100% CPU bug is present.
So to those who are claiming "it is fixed" could you be a little more specific. Please provide the OS, number of GPU, GPU models, and specific kernel example where the "100% CPU BUG" is "fixed".

Hey guys,
It is fixed in windows but Internally we found few more issues also in windows. i will let you know more information.

OK, so
1) When can we expect a hotfix?
2) When can we expect a final version?
And please don't start bulls**tting us!

Tristan23,
I cannot tell you time lines.
You should also remember that we are here to help each other. Not for some thing else.

First and foremost: Don't forget who pays your paycheck. That's us, the AMD users (that you obviously give a damn about).
We paid you (AMD) a lot of money for hardware that we can't use properly because of your crappy drivers!
If I don`t have a fix by the end of the month I`ll
1) send my AMD hardware back
2) claim damages
3) buy NVIDIA hardware
I hope other users will do the same.
Possibly this is the only way to make you arrogant %#&!"$ react ...

Raistmer,
We downloaded the 11.10 preview driver. I did not see issues with the applications i have.
How can i conclude your MB_bench_v208 is runing fine(giving correct results)?
I see following in log. What is the meaning of theses.
ERROR: The system was unable to find the specified registry key or value
Result : Different
Is it possible to get your application for testing?
