Why is my Hardware Accelerate Composition, Layer, and Footage Panels check box disabled

hello anyone!

 

i have requirements meet adobe's standards gpu requirements, check box (hardware accelerate composition, layer, , footage panels)[edit>preferences>display] disabled me, why? need worry setting? matter? information on topic helpful. in adavance feedback.

 

 

 

gpu information:

 

fast draft:	available
texture memory:	924.00 mb
ray-tracing:	gpu

 

 

opengl

vendor:	nvidia corporation
device:	geforce gtx 470/pcie/sse2
version:	3.0.0
total memory:	1.20 gb
shader model:	4.0 or later

cuda

driver version:	4.2
devices:	1 (geforce gtx 470)
current usable memory:	608.00 mb (at application launch)
maximum usable memory:	1.25 gb

 

computer:

windows 7 64bit sp1

24gb mem

i7 intel

 

 

 

feature support levels

 

there 3 tiers or levels, lowest highest requirements, of support:

level 1: opengl swapbuffer:
this level requires gpu can opengl 1.5, or greater, shader model 3.0, or greater. ati , nvidia cards, , intel hd graphics 3000 chipset (available in macbook air, mac mini, various windows machines, etc.) , 4000 (windows @ time) supported. if gpu not support these requirements, software os blitting cs5.5 occurs, , there improvements software blitting in after effects cs6, well.

level 2: fast draft previews, hardware blitpipe, , cartoon gpu acceleration:
includes level 1 features. level requires opengl 2.0, or greater (with shader model 4.0, or greater, on windows), , 256 mb, or greater, of texture memory. ati , nvidia cards released in past 5 years, plus intel hd graphics 3000/4000, support level.

if gpu not support these requirements, these features disabled:

• fast draft mode
• the "hardware accelerate composition, layer, , footage panels" preference.
  
• the cartoon effect's "use opengl when available" option (the cartoon effect runs on cpu).

level 3: ray-traced 3d rendering on gpu:
includes level 1 & 2 features (for machines attached monitors). level requires supported nvidia gpu , 512 mb, or greater, of texture memory. current list of supported gpus, see adobe website.

well, should concerned isn't available  - there still configuration issue graphics card - can live without of time.
