NVIDIA TechDemo X-Isle on GeForce 2 GTS

X-Isle Benchmark V1.02 is (C) 2000 Crytek Studios
X-Isle was released as tech demo for Geforce256 and Geforce 2. It shows the cutting edge feature of CryENGINE.
Recommended hardware is a Geforce2, Pentium II 333 MHz, 64 MB RAM.
The scenes compare:
- texturing with vertex lighting
- bumpmapping with per pixel lighting
- environment cubemapping in refraction mode
- environment cubemapping in reflection mode
The video was captured from a Pentium III 800 MHz, Gigabyte GA-6BXU, 256 MB RAM, ELSA Gladiac (GeForce 2 GTS), Win98SE, Detonator 12.90, with default settings 1024x768 16bit color depth, VSync Off.
The demo shows the current number of polygons rendered, current fps and some more statistics. Noticably the GeForce 256 performance drops rapidly as soon as the dinosaur with cube mapped environment mapping is shown.
The Geforce256 specs are:
Chipset: NV15 (Celsius) at 200 MHz, 180 nm
RAM: 32MB DDR SDRAM at 166 MHz, 128 bit bus
AGP 4x, Direct3D 7
Programming: Vladimir Kajalin
3d models: Andrew Dorr, Olli-Pekka Saastamoinen
Artwork: Timo Kujansuu

1999 released this demo scene, it's impressive that after 25 years the basic things of 3D still without changes.

Environment mapping scenes are 4 times faster than on the GeForce 256. Amazing progress.

@MrMilli I checked also against a GF2 MX400 and it also does not show a noticable slowdown if environment mapping is visible. Seems to be a really different performance behavior on the GF 256.

[@MrMilli]

@@MichaelHuth The feature is called Cube Environment Mapping but I can't find any info about why it's so much faster on the GF2. The pipeline must have proper/better acceleration for it or something.
