It works for my Gf4ti4200 w.o using vertex shaders.

Try this and see if something shows up other than black on the geforce. If it does... a screen??
water test 5

That one works.

works fine

so..... this is where it gets weird, and some troubleshooting is needed. I should post the code in a new thread. I will post the bare minimum that runs on my ATI and also the water_test_5 code to show the differences.

BTW: thats how that version looks on my ATI too.

runs on my gforce4!!!!! (didnt last time..black) will also test on my radeon9600 later...

GREAT JOB!!! so is this pretty universal then?

Your da KING!!
This is the first nice watershader that works with my GeForce4 Ti 4200!!!!!!
Goooooood work!

It's bumpy on plain Geforce 3 as well. The textures look a little bland though- 16 bit ones ?

Things have been so screwed up with that thing that I have not had the time to test different textures and different tweaks. The water_test_1 looks pretty nice on my ATI, the water_test_5 does look bland. But so far it was the only one to run on anything other than the ATI.

I hope that those with more knowledge than I can use the code as a start. To figure out what the heck is going on with these cards.
