hi everyone

for some reason, if "enable opengl drawing" is enabled, whenever i open up an image(it opens up at less than 100%; i.e. 25%) the image is garbled.
If i zoom in at 100%, everything looks just fine.

What I use:
Intel P4 HT @ 3GHz
Win Vista Ultimate 32bit
2GB RAM
Ati Radeon 2600 XT with 512 MB RAM

Photoshop CS3 Retail & CS4 upgrade.
Windows, Photoshop and video drivers are updated(manually checked).

Other things i tried: changing resolutions on my CRT monitor(usually i use 1600×1200; tried 2048×1578 to no avail).
I also tried disabling the opengl drawing and everything runs normally aka the images display correctly.
In other words, i believe there’s a problem with that option and display drivers. In one topic I found something similar with the resolution to let the application decide the settings to use. I’ve checked for something similar in ATI’s control panel, tried i think all 3d settings(enabling/disabling them and of course restarting photoshop to re-read the settings)…unfortunately i couldn’t get a better result.

On the other hand, my windows installation *might* be too old at this point and a reinstallation should be in order.
Anyway, if anyone has a suggestion I might as well try it out – got nothing to lose. Here is a sample of what’s happening:

Looks like a problem with the engine trying to maintain the sharp zoom (though I could discern this being females playing volley ball somehow) 😉 If re-installing and playing with the driver settings didn’t help, then probably a full system re-install may indeed be the only way. The only other thing I can think of is turning off Vista’s visual fancies…

ok, here is an update:

first of all, i didn’t mention where i got the latest graphics drivers: from ATI’s driver download page. In other words, even though the card’s model was the same as the downloaded driver, for some reason *some* features weren’t enabled(i guess).

today i tried downloading the latest drivers from the card manufacturer(namely sapphiretech.com) and surprise !!! it works like a charm !
