The one with FSAA is my shot. The other shot isn't from me actually. I took it from that link. Look at the bottom right of the shots.

And it wasn't run with an "anti-cheat" driver.

I was stating what I understood from the article. Some of us aren't as technical as you are. ;)

quote from article:
Only the modified driver with the AntiCheat script removes this veil of blur and offers an appropriate image quality matching the 8x anisotropic filter setting.

I'd just like to add that DM-Icetomb plays miles better in Linux and doesnot have the slowdown issue like in Windows.

Hope that sheds some light on the issue.

that's because the OpenGL renderer doesn't render every effect.

Like what and i'll took out for it, besides it's still slow in OpenGL in windows.

OpenGL does not render into textures as well a few other things. Ever notice why you have no more ammo counters on the guns that we had in UT :(

There is no rendering errors at all in Linux, OpenGL

do you understand the words in this post?

it simply does not render the stuff--no rendering "errors" per se because it doesn't even try. jbirney has pointed this out on numerous occasions (he's the head coder for ChaosUT. you do the math.).

Speak engish, "it simply does not render the stuff"

what are you talking about, what is OpenGL in Linux(UT2003) not rendering?

I cannot be expected to read every thread on the board so please explain what the hell your talking about.

there are effects in the D3D version of UT2003 that are not in ANY OGL version, whether it's Windows, Mac, or Linux. jbirney has a list of those. that contributes to the higher performance under OGL compared to D3D.

SuLinUX,

I have no doubt its a bit faster under OpenGL. OpenGL has always been ahead of DX in its overhead for just the API itself. However Danail V from Epic has went out of his way to soup up the OpenGL part of the UT2k3 even though its not supported. However there are some things that that the openGl part will not do. One of them is scripted textures. Thats were the ammo Counters came in on the UT guns (I have assumed you have played UT). They work fine in D3D, no workie at all in OpenGL. We used them to draw the players name you just killed on a tombstone. UnrealSpeed uses them to draw you name on the car's license plate. And they can be used as moving scoreboard (like in UT Morphues level).
Then there is the render into texture that does not work at all in OpenGL that kills things like Cameras and drawing a mini-hud on top of your real hud (and I had such a cool use for that). They also handle Firetextures and Enviroment maps (the effect that makes the tops of water) differently. There is more at Epic's UDN but not sure if thats in the public section or not...

Thus trying compare scores from the OpenGL path to the DX path is like comparing apples to banannas. Yea they are both still fruit, but still much different....

Thanks for that, But would anyone care to explain why OpenGL/D3D in windows is very slow in DM-Icetomb but in Linux it's normal?

Huh, why?

Seems no one has a answer for it, DM-Icetomb plays very nice in Linux/OpenGL 1280x1024 thanks but in windows it plays like crap. :D

It has been answered twice already :retard:

In this particular situation, if i got it right,
OpenGL is fast because it simply does not paint the details causing problems. It's like you set "Details Level" on LOW.

Uhm no.Better to say - Under Linux it does not paint all the details it paints under Windows. :)

Ohhhh commme on, please, details textures is there, fog is there, particles are there, shaders are there. everthing is rendered and looks damn nice.

what the hell is going off, right i'll post a fricking shot.

okay, we've explained it to you numerous times now, OGL does not render everything that D3D does.

Check out Phobos2 in D3d, then in Ogl. Those kewl little light trails that crawl all over the hull plates in D3d mode don't render in ogl, hence the speed increase.

Right thanks I know what you mean now, Yes I can confirm that.

What am I looking for in DM-Icetomb?

Questions

1. I know they are shaders but surely not a performance boost?

2. OpenGL in UT2003 is alot slower anyway even epic say that.

3. Does the Radeon render the effects in OpenGL?

the only question I can make sense out of is 3, the answer to which is no, because it's a game limitation, not a hardware or driver limitation.

It's gone quiet I wounder why. :rolleyes:

LOL no one can explan why DM-Icetomb is normal in Linux but plays like crap in Windows :lame:

SuLinUX I thought we went over this, no tinternet for you unless you eat all your greens and take your medicine.
SuLinUX
10-11-03, 06:59 PM
I've heard people say it's because of the FX's shader performance the reason it is slow. :rofl

OK you sit there and tinker with Linux while I.... OK you watching this?

/me loads a game and plays

Oh yes!!:p

huh?

Linux plays DM-Icetomb, OpenGL much better than Open/D3D windows, WTF are you talking about.
