with nvidia's new drivers and support for glsl, will this give shadering (the r_glow thing i guess) to linux users aswell? i know absolutely zero about this subject, and if gl shadering language is for an entirely different purpose you'll have to forgive my ignorance (:

Linux users already have rglow on GeForce FX's and Radeon 9000+'s.

I lose 80 percent of my frames if i enable shaders, i assume shaders written with glsl perform better.

Yeah, but rglow on GeForce 4 and 3 would be nice, eh?

I used the ARB_fragment_program and vertex_program for opengl modde because it is portable. Supporting gf3/4 would require me to write a special path for the NV_shader extension which i'm not going to do. If you want to use shaders on the gf3/4 then use Windows.
Unless the opengl driver is able to compile the shader to NV-specific functions, that's the way it's going to be.

Hi.

It seems broken in my case. I have FX5600 and after setting doshaders to "1" and turning the rglow on, my framerate dropped to ~10 FPS... Shader, well, it works, but it's so damn slow... Any advice?

I have an fx5600 on my windows sytem, and I take about a 50% framerate hit with rglow on. The FX5600 really isn't a very good card. It does not perform as well as my GF4 Ti 4200, except that it allows me to have rglow. I get 20-30fps with rglow on, and this is under directx. I'd reccommend just getting a new card. :D

We haven't spent much time trying to make things faster lately. Yes rglow is slow. It really eats up the framerate on the mac. With nvidia cards, it seems slower than it should too. I really don't know what to do about it right now. It's on my list but it's kinda low priority at this time. All I can say is to either deal with the low framerate or turn off rglow until we make it faster.

I think rglow is pretty, so I keep it on while exploring.
I have an alias to turn it on/off if I get into a fight.

That works well for me, but it doesn't exacly say "finished product".

I'm glad to see it's on the list. I'll expect it optimized "soon" ;)

I'm just happy the darn thing works now. Before it was rendered on-screen in the lower left corner. That was not pretty. ;)

[edit]
oh and shaders is lighting-stuff that make the transition from light to dark more smooth IIRC.

Radeon 9600 pro 128...rglow sort of works, but whenever I have it enabled, weird things happen with the light sources...like suns changing colors...

To use shaders effectively I think you're going to need at least a 9500... the FX series just doesn't cut it with its crappy shaders (the 9600 Pro beats the 5950 Ultra in raw, FP24 shader performance). The only way it'll work well on nVidia FX cards (note: the 6800s are quite fine at this!) is if they make a special FP16 path just for nVidia cards and shaders. rglow works fine on my Radeon 9700 and seems to go quite fast.
