The only problem I'm having is that this is way too much fun. Is there a patch for that?

My GPU by the way is ATI 9250, 128 MB, 64 bit

I haven't done a lot of tweaking yet, but I do have trouble with the larger scale models for some reason. The GPU gives errors with those (sometimes freezes). But again, I've only just started tweaking for my low end GPU. No problem though because everything works perfectly with the Alpha 40, which is the one I can fly with proficiency at the moment. I also flew the Edge with no problems except that it's pretty hard to fly

I had to set the detail lower for pano scenery and the plane itself to get stability, but the difference in visible quality is barely perceivable if at all (I haven't tried 3D scenery yet... pano is better for this purpose anyway).

But I'm totally happy with this. It works very smoothly.

I think I will buy a new graphics card after all (just to get rid of the GPU errors with some of the other planes). I was thinking either ATI x800, x850 or GeForce 7600GT. Selection is partly based on what I can get locally without ordering. Any opinions?

My 512 MB of ram by the way seems to be plenty. It's dual channel which should increase it's effectiveness (and it's running at a pretty fast clock speed due to my overclocking mischief).

Thanks for the really great RC sim... really nice.

Cheers

EDIT: I should add that it's possible although not that likely that there was a minor issue with my overclocking settings (I'm thinking of the handful of freezes in particular). I did notice that there was some big dustballs in the CPU heatsink which I've cleared away now (that could cause some overheating and freezes). In general I test my OC'd computers for stability very extensively (24 to 48 hour CPU burn in tests for example). I'll check the settings further, but for now I can't put the TX down A higher end GPU will fix the GPU errors for sure though (they were "VPU errors" reported in dialog boxes). But like I said before that's not prevented me from using the sim and getting very good performance from it. I'm really glad it's working well
