Thanks for the links. I need to try the 32bit installer and patch, since the normal "install on 32bit Windows, and move the installation files to 64bit Win7"-workaround didn't fully work in this case, as it lets me play only in software mode: the 3D hardware selection is apparently saved somewhere in the registery, and the NFS3 video test utility fails to run due to the missing registery key.
I noticed though that my NFS3 is apparently some "OEM version", ie. it originally came with some piece of hardware I've bought at some point (which would explain why I don't have a clear recollection of buying the game). At least the installation CD has "OEM" in the disc title. I hope the patch works the same on it.
In general I don't think there are many games where Glide has a significant advantage in performance or quality over hardware generated D3D. Glide has advantage for games where it's the only way to enable hardware accelerated gfx - so mostly for DOS based games.
Also for retrogaming purposes, if the Direct3D-acceleration on an ancient Win9x game fails on new hardware and D3D versions/drivers, the emulated Glide-support might be the only feasible way to get any 3D acceleration on that game. Carmageddon 2 is one such a case, albeit I am not sure if it had that "Direct3D mode does not work if you have an USB controller connected to machine"-problem already before.
Now that I remember, have people here used any of the Glide-enabled DOSBox versions? The nGlide has links to apparently three different sites, but I think at least two of them are cross-linked (pointing to the same Gulikoza's DOSBox variant), and one of them (Gulikoza's page) gets blocked by my virus scanner (Trend Micro OfficeScan), claiming it is a known trojan site or some such sh*t. Probably false positive, but there you go. http://www.zeus-software.com/downloads/nglide
Too bad at least one of the sites says the 3D accelerated version of Whiplash/Fatal Racing is still not working with the modified DOSBox, because for now that was my main motivation to try it out. :(
And on a similar note: how the heck do you uninstall DOSBox? I have DOSBox 0.74 installed (can be found in Programs), but I don't find any uninstallation option. Not under Programs, nor in Control Panel. I googled "DOSBox" "uninstall", and at least for earlier versions they claimed it should be possible to uninstall from Control Panel, but then I saw also some links to some utilities and manual instructions how to get rid of DOSBox completely.
EDIT: Whoopsie, it is apparently under "Extras...". I have no idea why I can't find it in Control Panel though?
