Yes, I see where you're going with this. I'll see what I can do about it, if anyone wants to suggest any game, I 'd be happy to oblige. I just procured Breakneck that meljor mentioned, I'll see if it runs properly on my setups.
Speaking of drivers, I see what you mean. That's actually a pretty good idea, I could perhaps compare different driver versions from a point when 3DNow! optimizations were not implemented and from another where they were, or even compare later drivers to earlier to see if they did any further optimizations.
There's only one issue with this. The Voodoo5 came out in mid 2000, so I'm pretty sure I can't do that sort of testing. In fact, I don't think even Voodoo3 would qualify for this, with a release date of Spring 1999, I'd be better off with Voodoo2 SLI, but in that case I'd be introducing a GPU bottleneck, which I'd like to avoid.
In other news, I am well underway testing and I'll probably finish up on the 333 today, depending on whether or not I have any annoyances in the day 🤣 . I also found out that Tomb Raider 3 had a 3DNow! patch, so I took TR4 out of the equation and will test Tomb Raider 3 instead. I'm not sure if they are the best of candidates, since they have a hard 30fps limit and I'm relatively sure I won't see performance dip below that in any case. I guess we'll see.
Don't be reluctant to suggest games because I'm finishing up on one CPU, these Slot 1 CPUs are so easy to just pop off and install another that it wouldn't be an annoyance in any way.
