So, having sent off my email a few hours ago I get the following reply;

Quote:

You are correct, the problem with using MRTs in OpenGL is a known issue and we have no plans to fix it in our current driver. Although there is a chance that this could be implemented in a different way in our Vista driver, we do not have any official word. Thus, I would suggest that you find another way to implement your project.


Excellent, well played ATI, well played.

Granted, while I'm using Vista (which, still doesn't appear to have a fully working OGL driver either) I'd kinda like stuff to run in pre-Vista OSes.. like, ya know, that huge XP install base...

So, my next card will be an NV one, because while I can forgive many of the smaller 'issues' this one directly effects me and plans for things I want to do.

Sorry ATI/AMD users; you just got screwed.

There was also that bug with ATI drivers that leaked a small amount of memory every time you called wglMakeCurrent.

Unfortunately if you wanted to write an OpenGL + wxWindows editor, you'd leak that small amount of memory every frame. In my project that added up to a couple of MB per minute. Imagine using the editor for a few hours!

While attempting to report it to ATI driver support, their site kept crashing and timing out, deleting my bug report. I gave up and vowed never again to go ATI.

I tried, dear God I tried, but sometimes it seems that companies just don't want to improve.

I think this bug was fixed a while ago now (6-12 months).
