Yesterday I installed Windows 7 (64bit) at my computer (previously it was running Vista). In Vista my version of Photoshop CS3 Extended was not slow, it runned quite well.
But now I installed Windows 7 the save function (of Photoshop, the usual ctrl+S) is really really slow. Windows even says it is "not responding" for a while. In the end it saves it, but way slower than my computer used to do with Vista installed (and it never showed not responding).
So I have been running task manager next to it for now. When I use photoshop for some brushing on the image the usage varies between 10% and 30%. when it gets stuck on saving the cpu usage was only something like... 6%
All settings are still default (since it is all freshly installed).
The image I was working on was 1400x2000px at 300 dpi. A PSD with 4 layers. It should not be this slow.
Other programs running were three tabs of Internet Explorer.
I have been searching on the internet too, but I cannot find really a good fix. I only came accross at something about a printer may be not functioning well, however there was no tutorial about it how to fix it (and that was not about saving, more about opening and closing files in photoshop).
So yeah, any tips on how to fix this? The file I was testing with was not even that big. It should be able to work "properly". But how?
