AHA! It seems to be a problem specifically with Shockwave/Director. I tried loading )p('s Sinistar Cockpit viewer on my cab, and I can rotate in real time, no prob. As soon as I grab the corner of the window and drag it all over the place, the machine can't seem to keep up with the wild scaling, and it freezes! This happens every time I try. I'll have to try my other Geforce card from my workstation, and see if that helps. Otherwise, I'll have to switch to a less demanding FE, or get a new machine... Dammit! I really liked 3darcade!
BTW, I tried unzipping the FE into a new folder, without changing settings. I loaded the FE and just let it sit there. The arcade loaded up, the ambient sound played for a minute or two, then the whole thing froze again. It seems to happen at completely random moments, sometimes during the initial FE startup, sometimes after I've played a game or two.
Also, I've tried wildly sizing regular windows and browser windows, with no problems. Only when I load a model viewer does it have problems while sizing. I've tried it on my 1.4 GHZ workstation too, no viewer problems and no FE crashes.
Hmmm...things may not a be a total loss. I can still view other Shoackwave / Director content in my browser without crashing. Is it just the models? Looks like I can still use the Emulaxian paging menu if I set show3dmenu to false, and showglcabsorpics to false. That way, I avoid the 3d models completely. No crashes so far... But I miss the FPS arcade!
