So I've tested this driver. I challenged it against Detonator 23.11, 27.00 & 27.10.
This was a good test for my new mainboard (Epox 8KHA+). Damn that board is stable as hell!
But now for the tests. I tested the drivers with 3DMark2001 with all options on. And I can say the 27.20 rocks!

The PC they were tested on was a:
AMD Athlon 1333@1460 (146x10) "Real Clock" 1467.61
EPoX 8KHA+ (KT266A chipset)
256 MB RAM PC2100
VisionTek GeForce 3 (Overclocked at 235/535)
Microsoft Windows XP Professional
DirectX 8.1

These are the settings I used:
All the settings were default except
Vsync = Off
Monitor = 75Hz

If the number is bold that's the highest score of the 4 tests then.

So the Detonator 27.20 wins the battle!
Not with much total score but with high polygon count very much.
I will stay with the 27.20. It's the best detonator for my system.
And it's very stable too so far.
So it's really worth to try.
(but every computer is different, so maybe on other computers they work good too)
TRY AT YOUR OWN RISK!!
