I am having severe problems with Photoshop CS5 x64, and I currently trying to narrow it down and suspect the dual GPU switch to be the culprit of it.
When I first start Photoshop after a fresh installation everything is fine. For testing purposes I leave it at default settings. After a reboot Photoshop crashes each time I open a layer style and try to save it (the layer style, not the document). Once I trash settings on Photoshop startup it works again (though I did not change anything about them beforehand).
I have read on other boards on other laptops with a dual GPU setting that they had problems with OpenGL not detecting the right GPU. I have the latest drivers, latest Photoshop and Windows updates. OpenGL is enabled in Photoshop and seems to detect the right GPU. The problem occurs even when I disable OpenGL in Photoshop. The nVidia GPU is enabled in the corresponding nVidia settings panel to be used with Photoshop.
My question: Can it be some kind of conflict with both GPUs being in used in Photoshop? Is that common and did it occur to someone else having a Lifebook with switchable GPU? And is there a way to explicitly force the nVidia GPU to be used for any window and process that is Photoshop (x64)? Or any path of a solution I could go?
Thank you in advance
Edit: Seems I have (re-)found something else that might be related. On first run after installing Photoshop (both versions) the program crashes immediately and some compatibility assistant tells me it has put compatibility settings on Photoshop to run from now on. After that Photoshop starts normal, but with said problems.
