I have a problem with CS4 under XP 64 bit. The ‘Enable OpenGL Drawing’ checkbox in the preferences is grayed out. I have a Radeon 4580 card which should work with CS4. I recently had Vista 64bit installed and there was no problem there… OpenGL worked just fine in CS4, just as it should.
But I can’t get it working in XP64. I’ve installed the latest drivers but still nothing.

Anyone have the same problem? or the same setup and got it working?

XP64 is unsupported so you’re pretty much on your own here. But I have to ask…why, if Vista 64 (which is supported) was running fine would you downgrade to an unsupported set up.

Oh, so CS4 does not support xp64? I did not know that.
Well the reason why I downgraded is because I don’t like Vista… there’s always something running in the background using the hard drive (to name one of many annoying things)

I think you can turn off indexing. Or better just leave it to finish – it really helps searches and once it’s finished it should be noticeable.

There again, you might have some anti malware scanning.

My Vista computer is totally silent.

I’ve been using Vista64 and it does not appear to have more processes running than XP, in fact there appears to be less. Just compared the two installations.

I have XP-64 and you can get OGL working. Just use the enable old GPU hack mentioned in other threads here.

I have found it to be about the same speed as CS3 without OGL enabled and slightly faster with it enabled. The filters work much faster and interoperability between LR 2.1 64-bit and CS4 64-bit is extremely fast. 64-bit filters like Neat Image are instantaneous. I am typically working on 16-bit tifs from the 1Ds MK II.

Presently working with Word, Outlook, Opera, PS CS4, LR 2.1 open and the task manager is running a total of 31 processes which includes three separate processes for the Wacom tablet and ESET Smart Security in the background.

The lagginess that others report is there with the rough round bristle brush at 100 and the dry brush tip light flow 66. There is no lagginess with the other brushes at default sizes. Some images, not typically large, with lots of adjustment layers and layer effects open slowly, sometimes a square at a time, but when the same file is opened on CS2 w/XP 32-bit it opens the same way.

XP-64 is not supported, nor was it supported in CS3. I have found that using the Wacom pen speeds up the brush response. Using a wireless mouse slows things considerably.

Stability is 100% so far and I have never had a crash.

See if it works for you. If not, go back to Vista 64.

I’m running XP64 and the open GL "hack" makes things work a bit better. But the speed difference between CS3 and CS4 is considerable on the same machine. I am mostly still using CS3 because CS4 does not work as fast on this machine, which is a Two Dual-Core 3.2GHZ Xeons with 8GB ram. I’ve got a dual boot mode with a clean XP32 Pro installation on this same machine and the performance of CS4 is identically poor on XP32 as it is on XP64. So XP64 in and of itself is not the issue. The brush tip issues also exist on both OS’s.

Thank you all for your answers, they have been most helpful! I went back to Vista (too eager to wait for all replies). I hadn’t heard of the OpenGL hack until now, so I regret not trying that one out first. But I don’t want to reinstall again. If I get tired of Vista I’ll try the hack with XP64. Once again… thanks!
