Gaming performance question - possibly a stupid one...

I started playing System Shock 2 recently. A great game but the oldest and first game I've tried with a 16 bit graphics engine. I also have Half Life, but there is a command you can stick in the .cfg for Half Life that gives you 24 bit, which is almost as tight as 32 bit. But for System Shock 2, it's just 16 bit depth, no way around it. So I go to a forum and they say up the resolution. A lot. So I raise it up to 1280 x 1024, which I've never done before; all my games look fine at 800 x 600 x 32 bit. But I was surprised to see at that high resolution that game looked perfect, as good as any of my other games at 32 bit.

So now I'm curious: which is better for performance? A high res (1280 x 1024 and up) + 16 bit depth,

or

low res (1074 x 768 and below) + 32 bit?

I guess a more general way to put it is what causes a greater hit on the card/cpu - high resolutions or bit depth?
 
It's not actually 16bit or 32bit color. It's actually 15bit and 24 bit (5bits per sample or 8 bits per sample). Now I could come up with a formula for which one sends more data to the monitor, but it wouldn't be an accurate predictor of which one is faster in games. Unless you know a lot about CPU and graphics processor design, the easiest way is to just benchmark the game you're running at both settings and see which one is faster. Run a timedemo at both settings.
 
Thanks, I didn't know that...
I figured just running a timedemo would answer that, but just wanted to know first if there was a general opinion amongst gamers....

I haven't used 16 bit for anything since quake 3 came out. 16 bit looks like crap, that's my opinion 🙂
