I have installed CS4 on a older XP 64 bit machine, video card is a nvidia GEFORCE 8400 GS. Machine is about 1 1/2 years old, 8mb of ram and
a dual core, not core duo processor.
The installation went fine and CS4 seems to run fine and process files, however when I view an image a 100% view and try to move it around
the image tiles as you move, and gets very jerky.
This happens in both the 64 bit and 32 bit versions.
I looked under the performance tab and my GPU settings are greyed out. CS4 says myvideo card drivers or card may need to be replaced. I
have upgraded the drivers, but not the replaced the card.
It's been a long time since I saw this type of problem on CS4 and I can remember some type of setting on tiles that used to fix it, but can't find anything
specific in CS4.
From my reading, I thought that that the GPU had issues with XP64 bit, with the 64 bit edition of CS4 and assumed the 32 bit would be OK. I also thought
that the GPU and Open GL was more to do with the 3D stuff, which I didn't plan to use.
I have not loaded CS4 on any other 32 bit machine, XP or Vista to see if the issue is only related to this one box. CS3 works fine, no issues with moving an
image around.
