I know there are plenty of threads about OpenGL problems out there, but most seem to focus on OpenGL not working at all. That’s (fortunately) not my issue. My problem is that I would love to use CS4 for texture painting, but 3D object interaction is just so unbelievably slow!

System: , Vista 64, 8GB RAM, nvidia GTX 260, driver 182.08

I notice that when I rotate an object, the CPU goes up all the way to almost 100%, all used up by the Photoshop process. And still the movement does feel far from fluent.
No compare that to any other OpenGL app, let’s say Mudbox or UV Mapper. No hitch at all, everything is fluid and barely uses any CPU. So it feels like all the 3D Object interaction is rendered by the CPU alone. The CS4 system information however says behind every OpenGL feature (Supported!).

So what gives? Anyone else having the same issue?

Ok, I take that back, if I use software only rendering by turning off OpenGL in the driver, it’s a lot slower even.

Are you using a Ray Traced render setting? That will use CPU and not GPU.

Also, do you use multiple layers in your document? If so try setting the 3D> Auto Hide Layers for Performance to ‘On’.
