Cat 11.2 vs Cat 11.9 on HD6950

<< < (2/2)

benool:
Thanks for testing and posting the results.

So if I understand this well, in case you don't usally run 100% on your CPU, 11.9 should perform fine even faster?

skildude:
No it appears that 11.9 is still a little slower than the 11.2

I hope the ATI guys get their act together.  I can't run 11.2 because it causes my computer to lock.  I'm forced to use 11.8 which is ok but like he said it has erratic time increases.  If they act on Raistmers information perhaps we'll see something in a couple months.

To check this assumption one should repeat same test with 1 core (of 4 in case of my quad) freed for GPU feeding, maybe 1 core of many would be not enough... depends of nature of issue - why idle-priority processes have so big influence on driver...

Mike:
IŽve seen a couple guys keeping 1 or 2 cores free to feed GPUs more efficiently.

At least i see improvement in the right direction.
Maybe weŽll see some changes in official release already.
