Sorry to hear that you experienced a performance drop with Crimson. I will guide you through the process to get your system back to its former glory.
- You can monitor GPU temperature via Catalyst Control Center > Performance > Overdrive. The 295x2 should run at a maximum temperature of 74c. Once it reaches this temperature it will throttle to prevent higher temperatures and damage to the graphics card.
The most recent Catalyst driver is 15.11.1, available for download here.
I would recommend uninstalling the current drivers following the guide here.

Thanks for your reply. I have been using GPU-Z and have noticed my fan speed in game increases to 27% and temperatures run around 57 degrees which seems safe enough. I believe I am still running less fps than what I was running on back Catalyst, guess I will have to un-install as you say and revert back to the Catalyst drivers to compare.
Is there any evidence that the Crimson drivers has deteriorated the performance of the R9-295x2?
sorry to hear you're having issue with crimson, i personally run two r9 295x2 and use crimson 15.11.1 drivers and have had nothing but gains from the new drivers .
