it started about a week or so ago but when i tried using the lighting effects filter rather than showing a shadowy gradient effect like it usually does it is either pue blakc or just shwos an unnafected picture and when i play with the lighting rig or change slider settigns like texture for example it flickers back and forth like it's broken
i tried searching to see if others had a similar problem but all i got was that CS6 either didnt coem with it installed or the app doesnt display correclty. i dont know what to do i dont want to keep goign to an older photoshop just to use it's basic features.
Can you verify that your CS6 is opening in 64-bit mode? Lighting effects in CS5 was not written for Mac 64-bit. CS6 had a revamp to 64bit support for Mac. This is the first thing I can think of asking you.
Apart from this, I doubt your Graphic Card support for Photoshop.
i am not sure how to check if i am in 64 bit and my graphics card is NVIDIA GeForce GT 330M. and it did used to work until like a week or so ago so i have no iea if soemthing chaged. also i recently downloaded a patch but i dont know if it worked. what cna i do?

it says nothing about bit versions. unless thats what version means. but i dont know how to read it.
Open Photoshop CS6. Then Open Activity Monitor on your Mac. Search for Photoshop. One of the columns will show you 'Kind', where it will show you if its Intel (64-bit) or not. If it just shows Intel, your app is running on 32bit.
yes it is 64 bit. and i googled for a way to look for it an i found out ther eis no 32 bit for mac. so now i know i have 64 bit what should i do? get 32 bit find a patch/update not use light effects at all?
I'm trying to reproduce the file you're working on. Can you help us understand the properties of your 2 other spot lights you have on the top of your canvas? Or, maybe, can you delete them and just try adding 1 light to reproduce your scenario and let us know if the issue still persists?
oh those other spotlights were just a preset i chose, Three down i think it's called,with the only modification was the texture setting turned on highest. i should have chosen the default to display but it happends regardless of settings.
even on default it still flickers. Chris Cox says it may be a driver problem though.
Not very common.
Are you on a laptop that might have switchable GPUs? (GT 330M is usually a moble part)
If so, have you tried disabling automatic graphics switching in the OS preferences?
Which OS version are you using?
Did you recently upgrade or update your OS?
