Well, the video card issues seem to have been resolved, and then in a way that allowed me to hold on to the Sapphire Radeon HD 3850. which is good; this new idea I’m chasing will need as much video performance as possible.

Of course, getting things to work was something of a task. It ultimately required removing all ATI software and drivers from the system, running a program to clean up any driver “remnants,” and then installing new Catalyst drivers (version 8.7) from a hotfix I managed to unearth from the Sapphire website.

Of course, that was only most of a solution.

Neverwinter Nights isn’t exactly a new game, and so does not require or support some of the newer graphics features that modern video cards can deliver. In most cases, of is easy to correct for this; in the case of an ATI card, using Catalyst’s control center to set all the advanced 3D features to be “application controlled” (where possible — “off” where necessary) will typically do the trick.

So I did this.

Neverwinter Nights started up just fine, loaded the test module just fine (a good sign: the module loading process had been where I’d been having issues) and displayed the scenery graphics just fine. But: no character models were visible.

Frak.

A bit of Googling turned up a solution I wouldn’t have expected, however. It seems that with this video card and driver set, it is the case that the Catalyst A.I. is apparently necessary to run in its advanced mode. That struck me as unusual when I first read it, but making the change worked…the characters were visible during the next test run.

Apparently this also has something to do with a setting in the game concerning environmental mapping onto character models; since I had this mode enabled (it maps “real time” reflections onto metallic surfaces on each character’s armour or clothing), that may also have had something to do with the missing models.

Eh, whatever. It works now, which was the goal. ATI drivers have never really played nice with BioWare titles, so I’ll probably have to monitor the situation like a hawk in the future. And there is this pesky issue with the mouse cursor’s repainting that I still have to sort out.

But it works!

I hate being beaten by a computer problem, so it’s nice to have put this one to rest.

So I have a conundrum.

Suspecting that the source of my Windows computer’s instability might be the existing video card (a Radeon 9600 XT), I went and picked up a Sapphire Radeon HD 3850 — pretty much the most powerful AGP graphics card in existence today. (ATI has always been my preferred brand.)

Anyhow, I installed the card and its drivers, and proceeded to test out Neverwinter Nights. That’s where the trouble started: NWN crashed, every time. I did some digging, and found a few hints in various places that the issue may have something to do with ATI’s Catalyst software — certain versions of the control center application evidently conflict with NWN, for example.

Things got worse when I tried to switch Catalyst versions (Sapphire ships the card with what I believe is Catalyst 8.4). Reverting to Catalyst 7.11 (apparently a very stable version) was no help: the driver didn’t support the card. Installing the Omega Drivers — which use Catalyst 7.12 — didn’t work, and for the same reason.

Installing the Catalyst 9.4 update/hotfix from Sapphire didn’t improve things any. And to add insult to injury, the Cayalyst drivers that can be downloaded directly from ATI’s website actually don’t support the card in question (it’s a relatively new card from Sapphire: AGP support and 512 MB of DDR3 memory).

Nothing seems to make NWN work. Which is a pain, as I’d hoped to start work on a new idea that would have greatly benefitted from the enhanced performance the HD 3850 promises.

A bit more searching today furnished me with downloads, from Sapphire, of Catalyst 8.7 through 8.9, and I’m hoping one of these will do the trick. Failing that, I plan to try reinstalling NWN, to see if that could somehow be the issue. I’ve already tried the critical rebuild patch for NWN 1.69.

Failing THAT, I’m thinking of maybe trading the card in for an eVGA nVidia GeForce 6200 LE and another 1GB stick of DDR RAM (this doubling what the system is currently equipped with).

nVidia cards apparently play nicer with BioWare games in general, although the 6200 is not as powerful, by a fair bit, as the HD 3850.

In the end, though, raw power is less important to me than that NWN runs, preferably at a frame rate in excess of 30 at a resolution with at least 600 pixels vertically (720 preferred) on a 16:9 monitor.

Thoughts? Should I even waste time on the HD 3850, or should I just swap it for the 6600 and the RAM? Has anyone else had this issue before and resolved it successfully?
