I have a Dell XPS Studio Laptop running Windows 7 with an Intel Mobile Core Duo T9550 Processor with a CPU of 2.66 GHz, I have 8GB of DDR3 RAM and a ATI Mobility Radeon HD 3670 Graphics card. Recently I purchased a large Intuos 4 Wacom Tablet and have been having troubles.
I've tried using it in both Corel Painter Sketchpad and Photoshop CS5, and both of them have lag. With Photoshop, I do a stroke, and then the actual stroke shows up half a second later. With Corel, I do a stroke, and it doesn't seem to register that I'm actually putting pressure on until half a second later, at which point it draws fine, this is with fast, repeated strokes.
I contacted Customer Support about this but all they did was tell me that the problem was with my computer, that my specs weren't "up to snuff" to handle it smoothly. I already new that it was a problem with my computer, because I've have this problem with another completely different tablet I had borrowed.
However, I'm a little skeptical that it's the Specs of my Laptop. I specifically bought this laptop because it boasted that it was a was good for Multimedia, So I would imagine that it should be able to to handle a tablet driver like this. I have noticed, however, that my computer mouse is also lagging in Photoshop, and I don't recall it ever doing that before, not only that, but my mouse works fine in Corel.
Is there a way to fix this lag, besides investing in a new computer? I've tried disabling the default Tablet Driver for Windows 7 because it can conflict with the Intuos Driver, but after disabling that, I still got lag. The Tech Support said to close all other programs when using the program, and that was about all the help he gave me. Any more help would be greatly appreciated because right now, the tablet is basically unusable.
Update: Allocating more memory to PS in the Preferences Panel and enabling OpenGl Seemed to improve it very slightly. I also downloaded and installed the latest driver for the tablet, but there's no difference.
