https://github.com/Bufius/vertminer-gpu.gitrelease notes:
Version 0.5.3 - 2 February 2014
- changed automatic TC calculation (again but still not finished / perfect...)
- increased max intensity to 21
- shaders are now used for intensity calculation
--> option shaders is set: intensity calculation tries to align to shaders count (can increase performance but also decrease with low intensity)
--> shaders NOT set: old cgminer intensity calculation is used
- opencl changed to keep speed with adaptive nfactor
- introduced first time dependent nfactor changes in code (not finally done yet)
- fix for ADL with R9 cards
lets see if we can get improved mining performance

Updated from 0.5.2 to 0.5.3 and working fine. Hash rate has increased 10khs per card, R9280x.
Cheers
What hasrate are you getting atm? I'm hashing for 350-355 per card.
