Thanks for the good news!shadywack said:As of 10.7.2 beta 11C37, OpenGL works after sleep. Slight performance increase.
There's a new GLDriver that also has OpenCL support "out of the box" for my 570. This is definitely a new driver for us to look forward to.
I confess I was too focused on thresholds values from MacBook 6,1 and 7,1 and called the AGPM from InsanelyMac faulty too early. I found out somebody just took original values from a NVIDIA GT120=9500? (Vendor10deDevice0640) and put them into their GTX 580.
Interestingly even the very same card differs on machine models (Threshold_Low::Threshold_High):
MacPro4,1 = 95::88
MacPro5,1 = 97::93
So I wondered why is that and why does the "faulty" AGPM indeed work. In my opinion the G-states are changing too often and it skyrockets till G-state 0 too easily. I wouldn't call this efficient, because those values were meant to be used for a much older and slower card. I think the GTX 5xx series deserve some better and just more power efficient thresholds.
I checked the behavior of the GTX 570 on Windows 7 (AERO transparent windows and visual quality all maxed out) and newest nvidia drivers.
Windows only seems to use three out of four G-states Mac OS X mentions in AGPM.
(Core::Memory::Shader)MHz
G-state 3 = 50, 67, 100
G-state 2 = 405, 162, 810
G-state 0* = 732, 950, 1464
*Looking at the power consumption I'd say it's 1, but the core, memory, shader clocks are maxed out so it should be 0. Hmhh....
The "thrilling part" was how G-states changes occurred under load and idle. Falling down one G-state took about 12~15s. Depending on the load it went up one or more G-states in less than a second.
"Skyrocketing" to G-state 0 only happened when the GPU was above 70% load!!
Comparing this to Mac OS X whereas many older cards' thresholds let the card jump to this state when GPU load is above 12% = L*
* L=I-G
(I=100% GPU Idle) (G=Threshold_High=88%) (L= % GPU Load)
Back to the drawing board for me. I am going to release a revised threshold table for power efficiency and performance soon.
+++Question for you folks+++
In TimeMachine when opening and closing images with QuickLook it lags for me even on G-state 0 (maximum performance mode of the card). No matter what I try it's never smooth!
Is it smooth for you? Maybe with an ATI/AMD card?
