Hello,

I was looking the swaaye youtube Riva 128 test with 3DMark2000 ( link https://www.youtube.com/watch?v=Cqxia9tPFrs ) and actually I'm testing the ZX AGP card with latest 4.11.01.0337 drivers but there's an interesting difference after my demo test and is the final epic water scene where in my test even with the vga "D3D - Best image quality" option enabled doesn't show water reflections and the water is trasparent with only the waves effect. The early scene where there are the boats has instead the same floor textures artifacts. But again the background polygons effect at 01:45 seconds isn't visible but totally black until it starts the new scene.
The drivers package I'm using are 15 files dated March 22 1999 7:05pm and Certified. Is it the right final one? Might be a different 3DMark2000 version (the one I'm testing is the V1.1 Build 340)? Or the ZX version render that effect different from the classic Riva 128 chip? Maybe I need to install a different Directx version instead of the basic 7.0 one?
Thanks

My config:

Pentium II 400Mhz
i440BX ECS P6BX-A+ v.5.6 bios
Riva 128 ZX AGP 8MB (usual cheap PCB)
256MB PC133@100
40GB IDE disk
Windows 98 First Edition and Directx 7
3DMark2000 (latest version from Legacy Futuremark homepage)

The bench score @ 640x480 16bit/Triple Frame Buffer is 943 points. Can anyone with a ZX version of this video chip test it too? It'd interesting that the older video chip had a different rendering on such "modern" benchmark.

😀

The "mistery" of the missing effects is solved. It looks like the default Direct3D control panel speed/compatibility options flags are all checked in these last drivers but for that Directx7 benchmark I had to remove three of those options leaving only the fog emulation one. Now both the missing effects in the Demo appeared. The water looks much more reflective (like "liquid metal" almost not transparent) but much better than before. I didn't test the speed impact.
Anyway the Thief II flashing textures in some rooms still is there and no fog in-game seems existing anyway. Impressive the Quake3 Demo test in game experience at the same speed level of the Rage Pro Turbo (middle/high details) I'd say and quite good rendering too in its own way of course.
