Well, It build that DX patch to people here to get little less stuttering on DX10-11. It won't hurt to test it before going to next driver + I know it will kill the idea of stuttering as much as it can under 10.9a. It's not very ideal in any sense because original 4.22a has totally another style of optimization. Hell, it may not work for BF:BC2 very well, but that is not really an module issue it's the driver itself. I am atm, running test build now here under new edition v4.22b. I will update it up soon enough. As for 4.70 well, it just feels really good build for even single cards as I was testing it for CrossFireX same time I tested it under single card setup. However, that build is still using the same driver and as said problem is in the driver. -edit- I will be since I now know how the new 10.8/10.9 series work be re-punctuating the v3.95 as v4.22b. I tested just 5 minutes ago and I can now confirm that 10.9a driver was the core issue on everything. -note- Heh, I was relooking on v3.95 (looks like history will teach us). Seems, back then I've clean hit the nail in the head. My current notes on optimizations and new stuff there is resamples v3.95 exactly. It does what I couldn't do with the v4.22a I build up from new drivers. This is really curious as this means also that new CCC editions and profiling is involved under degrading gaming speed. We are gonna be using OLD profiling (or no profiling at all). This new profiling seems to be the one which does really damn nasty damage under several game speeds. -UPDATE - v4.2x HD5 drivers- Ok, found solution. New driver will be uploaded today asa I've rebooted 2 times now. Newdriver will 100% sure be based on 10.8 WHQL and it will be based on v3.95 build with current understanding of of ATI driver team versioning. As I said we are missing 1 full driver here we only have 3 out of 4 and 10.8 WHQL is the last of it's breeth. -UPDATE - v4.7x CFX/EyeFinity drivers- This driver will not be updated for the moment being. I will update a bit better concept here next on processing and this takes a bit studying. Could use one of you guys to check me in. When I finish building so that I would know I am on right track. -UPDATE - v1.0x HD4 drivers- I will also update v1.08 build to reflect for HD4 and improve it's optimization. Driver WILL NOT change, but I WILL NOT build an patch. I will include new cleaning systems and other new stuff under new edition v1.12. Also this build will be added as 'expermental' most likely as I will not perform any testing upon it as I don't have the hardware to do so. However, my current notes/understanding under new builds is begin to be really good level. So, I believe I can build this now blind. In General: Looks like there was few mixed variations by ATI originally (which I ain't surprised) which originally since v10.8 started to drive to wrong direction. Got now pretty good idea where I took the wrong turn and will correct them on corresponding drivers for each hardware setup. As it's weekend now and no party on my windshield think we get some serious stuff done, if I just can get couple things tested while building on different style system setups.
