Test setup

All of today's testing has been run on the following:

- Intel Core 2 Duo E6600
- 2GB Corsair PC6400 DDR2 RAM
- MSI 975X Platinum PowerUP Edition (Socket LGA 775, PCI Express)
- 250GB Western Digital Caviar SE16 hard drive
- Sony DVD-ROM
- NVIDIA GeForce 8800 GTS 640MB
- NVIDIA GeForce 8800GT 512MB
- 1000W Thermaltake Toughpower power supply
- Windows Vista Home Premium (64-bit Edition)

The following drivers were used:

- NVIDIA ForceWare 169.04 and 169.09 Beta were used on both the GeForce 8800 GT and GeForce 8800 GTS graphics boards

The drivers High Quality texture filtering mode was enabled on the NVIDIA boards for all testing.

Image quality

Our first port of call for today's testing is, naturally, image quality, to ensure that all now looks as it should be with regard to water reflections in-game.  So, to test this, we've utilised Crysis' built-in GPU timedemo with all in-game detail levels set to 'High', taking a screenshot from the same frame of this run-through first with an executable name of 'Crysis.exe', then again with the EXE renamed to 'Driverbug.exe'. 

Click for full-size image

As you should be able to see, regardless of the executable name image quality is now equivalent, with water reflections rendering correctly in-game, proving that the issue in question is now well and truly fixed.

So, what (if any) impact does this correction have on performance?  It's time to take a look.
