Originally posted by: Raistmer I rebuilt my app with SDK2.5. But new binary shows absolute same behavior as older one: good performance and low CPU usage under Catalyst 11.2, greatly increased CPU time and elapsed time under Catalyst 11.8 preview. What can be done to improve performance under new drivers?
It is known issue and will be fixed in upcoming catalyst drivers. Please check catalyst release note whether it is fixed or not.
Any hope for some hotfix?
There were few Catalyst releases already all with this issue.
For my own GPU I'm forced to stay with Cat 11.2 cause later drivers have too bad performance...
