open gl has become disabled and preferences window doesn't show the detected video. card cache level is set to 4. help>system info still shows the card and drivers but I can't use any of the open gl features. I have already downloaded installed the latest drivers so Im not so sure that that would be the problem.
I know my graphics card supports it because I was using the rotate tool on this same document yesterday. How ever when i started it up today It no longer worked. I haven't installed anything since I used the rotate tool last (except for the latest drivers for my nvideo geforce gtx 460 gfx card, how ever this was an attempt to fix the problem)
I tried running the 64 bit verision of Ps but the results were the same.
My system is running
windows 7 64 bit
Intel core 2 duo 3.0 Ghz (dual core processor)
8 GB ddr2 ram
Nvidia GeForce GTX 460
(with 2 identical moniters connected via dvi)
Adobe Creative Suite CS5 Design Premium
Wacom Bamboo pen and touch w/ matching drivers
Belkin N52TE gaming pad with photoshop short cuts mapped to it.
Im not sure what else I can list that might be related
I made no system changes since the last time i ran photoshop.
I unplugged the wacom tablet for 5 minutes last night in order to install the drivers on another computer and when it was done i moved it back (Im fairly sure this couldn't have caused it but better to give all the info i guess...)
I would greatly apreciate any help you might be able to offer.
ok so I got it working again by doing an unistall and then a clean reinstall of the gfx card drivers . Later I closed photoshop and shut down my computer for the night. I came back the next morning and once again photoshop does not see my gfx card under preferences and won't rotate images...
some one i know suggested that I try an older driver in case it was a bug with the latest one. I did so and once again It worked untill i closed photoshop. I closed and reopened the program to test it and sure enough when i reopened it all open gl functionality was gone once again. I don't believe nvidia drivers are the problem because i have tried 3 different version with the same results. each one works untill i close photoshop and the second time i open photoshop it quits working.
do any of you at adobe have any idea what might be causing this?
Adobe is kind of tight-lipped about specifically what causes the various features to be disabled, except that they say that failures/crashes in the display driver are noted and the functionality of the GPU is de-configured. Photoshop essentially determines that it doesn't like the way the OpenGL / graphics system is working and doesn't want to pass along a bad experience to you in the future.
If you can get back to where the Advanced Settings are configurable, before closing Photoshop try changing it to Basic mode.
Thanks for the reply.
I got through to an adobe employee on the live chat support system and while they were collecting information i noticed that there was an extra display driver installed.
It seems a program that was ment capture the moniter output as video had installed a driver as a go between and that was telling photoshop it couldn't do open gl.
I disabled it and all seems to be working again.
It may not have been the problem they thought it was but it helped alot to walk through all settings and things i thought i already knew.
I hope this helps any one else who runs into the same problem.
Interesting that a mirror driver should cause it to work, then not work like that.
I probably should have requested you display the results of a Help - System Info request - that would have shown that driver and probably led to a solution more quickly for you.
Thanks for following-up about what it was that got it working.
