Ok, so I can't close the lid any more, and I need to be a little careful about not snagging the cable in case it does damage to the unsupported card, but now I have shader support! I dialled up full shaders (non of this shaders-lite for me!) and took the ol' Gunboat Diplomat out for a spin.
Wowowowow!!! GOOOOD stuff! Finally I can see what all the fuss is about! I was so overjoyed I went and downloaded a bunch of eye-candy-ish oxp's that I hadn't worried about before and installed 'em all. Then I had some fun mucking about with gamma settings, but I'd been meaning to do that anyway once I had a card that let me play with such things.
The result? All I can say is... fan-friggin'-tastic! Elite IV stands no chance, IMNSHO!
The various ships are just beautiful, the Black Monk Monastery is amazing, and there just aren't words to describe Griff's Trade Outpost!
I was so blown away by my fly-bys of the TO that I went and got the great little open-source tool CamStudio so I could record it for posterity. It took some mucking about trying different settings and codecs, and I'm still not totally pleased with the result, but I got about 4.5 mins of footage I'm willing to release to the public.
So, here it is... It's recorded in 1024 x 768, so by all means watch it in full-screen mode if you wish (that way you can even see the background stars

I managed to capture 3 ships exiting the docking bay as I went past. If you watch closely, you'll see the second one (a Viper) take a potshot at an Ionics Huntsman, execute a quick looping 180 and bug out, almost immediately another Viper exits the TO and takes off after the Huntsman.
Man, how I LOVE this game!
