Far Cry water

[crusher_pt]

Err... i have a question about the subject of the thread.

When you set the water quality of the game to Ultra High, it uses PS2.0? Or only the PS2.0 are used in the specular/lighting stuff of the game?

Thanks

Water doesn't use PS 2.0

the general use of ps 2.0 in farcry depends on the lighting quality setting in advanced video options menue afaik.

you can check the log file in farcry root directory for ps 2.0 usage.

Even at highest quality settings, FarCry doesn't use PS 2.0 for the water.

That was pretty interesting. I thought that Far Cry would have a lot better visuals on a DX9 card. Hmm, i guess it shows that Far Cry in it's current state is'nt a good measurement for DX9 performance. Though that will likely change with the patch/addon.

Half Life 2 will be of course be very interesting. Even more if it includes HDR rendering using FP blending on the NV4X.

I thought Valve has said it uses HDR with integer formats on NV3x, so NV4x's FP blending might not even be needed (ignoring the performance hit and focusing solely on simply employing HDR).

AFAIK, FP blending should be faster then using integer formats since the integer version uses lots of shader passes.

according to valve HDR might not be included in the initial release of HL2

Sounds strange in light of all the hype about it when the benchmarks was released.

 

[Guden Oden]

Why wouldn't HDR be included? Surely the engine must have been finished long before the actual game.

 

[ZoinKs!]

I vaguely recall them mentioning something about "performance issues" when HDR is used.

And the Source engine does have support for HDR, but it won't be used in HL 2. Perhaps it could be added in a patch later on.


edit: Now that I've read tEd's link... that explains it all right there.

AFAIK, Dave mentioned that he asked nV about FP blending speed penalties, and Mr. Kirk or another engy hinted at half-speed performance. I wonder if int's multiple passes outweigh FP blending's halved theoretical performance (and probably greater memory usage?).

When the water is set to ultra high the water reflects every single object in the scene. When it is set very High it only reflects Things directly on or next to the water. Set it to Ultra high and drive arounnd in a boat. Its freaking crazy. Sky mountains every little detail reflected perfectly.

Simply awesome.

You'll get half the memory bandwidth but then it's a question if that will lead to half the performance in shader intensive games. Some knowledgeable people on this forums didn't think it would come anywhere near that. But it will be really interesting to see what happens assuming that Valve add's support for the FP blending version also.

Whether HDR makes it in or not hasn't yet been decided. It's a feature that mainly the really high-end cards can use well

I thought that the Radeon 9700 would have no problems using HDR. And that's more of a mid end card these days.

uhm, these aren't reflections really.. we should do a bitwise comparison

no, really, it isn't that much work. it halfs the speed overall at MAX because its just one reflections. there are more complex things... (but it does look nice)

Well thanks for the posts.

Another question... what´s the command for demo recording? I tried to find over there, but none. I remember to see in some place, but no luck...

Thanks!

Parece que não tens nada que fazer...

Here's a great tweak guide explaining all the advanced settings in Far Cry. Yes PS 2.0 is best used with 'very high' lighting. If you want to really see some great water detail/action set it to very high and make the update as fast as you can get it through the config file.
