XOpenGL OpenGL3 / OpenGL4 renderer for UnrealTournament

[sn260591]

1) I receive too bright screen, even after installation of brightness in game on a minimum.

2) Detail textures consist of one layer instead of two.

3) GammaOffsetBlue, GammaOffsetGreen, and GammaOffsetRed parameters don't work any more.

4) Fog affects differently on meshes and bsp:

[Smirftsch]

Sure you installed latest shader files? Low brightness should make it almost entirely black, so I am really wondering how it can be to bright. Maybe need more information what you mean.

but for

2) Yes, that's normal and was only changed in later utglr's (by me) to have more than one. Current method only allows traditional, 1 layer method.
3) It's not existing anymore currently. I don't see the need for it anymore also to be honest.
4) That was always the case and also different in "old" renderers. Lighting and fog are differently implemented for BSP and meshes. Perhaps it displays different now so that you noticed it

However, you can modify all about gamma directly in the shader files, check out for

Code: Select all

// Gamma
TotalColor.r=pow(TotalColor.r,1.8-Gamma);
TotalColor.g=pow(TotalColor.g,1.8-Gamma);
TotalColor.b=pow(TotalColor.b,1.8-Gamma);

in DrawGouraud.frag (meshes), DrawComplexSinglePass.frag (BSP) and DrawTile.frag (well, the "rest").

Will upload a new version again soon, added fading out for detailtextures like in the other renderers.

Two screenshots for comparison:
d3d9 with Brightness=0.400000 (I prefer this setting)

xopengl with Brightness=0.200000

2) Yes, that's normal and was only changed in later utglr's (by me) to have more than one. Current method only allows traditional, 1 layer method.

Two layers were used in all the renderers. Is it possible to do the same in xopengl?

4) That was always the case and also different in "old" renderers. Perhaps it displays different now.

In xopengl fog isn't capable to hide meshes completely:

But in d3d9 fog hides meshes and bsp without distinctions:

The implementation for gamma is quite differing from the other renderers- but can surely darken it some more depending on level if 0.0 or 0.1 is not sufficient.

This fog problem I fixed already here, sorry, forgot it isn't in current UT build yet.

I have set the brightness to 0.0, but the result is all the same a little brighter, than it is necessary to me. How can I change the brightness in shaders?

[Smirftsch]

the values I mentioned above:

Code: Select all

// Gamma
TotalColor.r=pow(TotalColor.r,1.8-Gamma);
TotalColor.g=pow(TotalColor.g,1.8-Gamma);
TotalColor.b=pow(TotalColor.b,1.8-Gamma);

the 1.8 in this case needs to be lowered. Depending on what value you have, you may want to change it to something like this:

Code: Select all

if((PolyFlags & PF_Modulated)!=PF_Modulated)
{
      // Gamma
      TotalColor.r=pow(TotalColor.r,3.6-Gamma*2);
      TotalColor.g=pow(TotalColor.g,3.6-Gamma*2);
      TotalColor.b=pow(TotalColor.b,3.6-Gamma*2);
}

To have a wider scale with Gamma (which is is having the 0.1 steps).

* Fixed hopefully remaining fogging issues
* Fixed some performance issue causing very short stuttering sometimes.
* Fixed some memory cleanup issue
* Shader cleanups, using a global include now.
* Thanks to han, sharing experience and code I was able to integrate full support for UED.

that's rather unexpected. Can you give me a log?

Operand (conversion of FP variables) problem in the shaders.....

[Smirftsch]

gah...

replace in DrawComplexSinglePass.frag, DrawGouraud.frag and DrawTile.frag

if (DrawColor != 0.0)

with

if (DrawColor.x > 0 || DrawColor.y > 0 || DrawColor.z > 0 || DrawColor.w > 0)

pretty much at the end of the file.

Not sure yet anyway if this will be final solution, it's for editor only now, so probably not. Nvidia and Intel I think which I used in between made this without problem, only AMD complains. Guess it's not fully valid after all.

You can't compare with "==" or "!=" FP values.
It's a classic programming error :p (FP values are not "perfect numbers")

[Smirftsch]

Oh, that's perfectly valid here since I really only need to know if one value is > 0, which is only for editor selection the case.  I don't need any real near or equal FP comparisons here. It's just that Intel or Nvidia allow me a method for that I found pretty handy, AMD doesn't.
But as said, I want to clean it up some more for editor anyway.

Although, while looking at it, just to check that

DrawColor.w > 0.0

is absolutely enough.

[shoober420]

Is there a Linux build of this?

[Smirftsch]

for the 227j beta there is, for UT not yet due to the ancient toolchain needed. Also its working with SDL2, which I need/want to migrate to UT then as well. Will attempt to make a build though, just can't promise when.

That's great news. I migrated to Linux recently and got Unreal Tournament & Unreal Gold up and running. It would be epic to have an updated OpenGL renderer for them.

[Smirftsch]

XOpenGL1.0.0.9_UT4.36 available.
Added OpenGLVersion option, to switch between OpenGL3.3 Core and OpenGLES3.0, some (low end) graphics card rather support GL ES than 3.3 Core, also performance may differ for these. Some OpenGL extensions like UseBufferInvalidation are unavailable for ES though.
Moved some intensive calculations into shaders (GPU) in order to reduce CPU usage quite some, this will increase overall performance especially for weaker CPU's when using XOpenGL.

Hi,

Thanks for the effort. GNU/Linux port of UT desperately needs an up-to-date renderer. The most recent renderer was ported from UTGLR'e OpenGL renderer which is quite old for modern distros; lacks many options and many preferences are now broken.

I am volunteer for alpha/beta testing if needed. Thank you.

Regards.

AMD Radeon HD 7850

OpenGL ES -> 100 FPS
OpenGL "Core" -> 25 FPS

Same spot, same settings.....

With a GeForce 750 Ti over9000 FPS.....

Which pretty much confirms what I said although I am not sure why the 7850 behaves so bad compared to the 750 Ti.

yeah, I'm very much aware about the poor situation for Linux currently, but can't give any promises at the moment when I will find enough time, life doesn't give me a rest right now.
The entire toolchain is older than any debian release and that speaks for itself. All Linux build would require a recompile in theory...

PS: Welcome here

[lowenz]

No video output, black screen (but the audio is playing!) with a GeForce 9600M (mobile system with Windows 10 64 and lastest drivers for the 9600M from MS Windows Update).

No difference between "Core" and "ES".

OpenGL message closing UT manually with "quit" command:
"too many errors", LOL

[lowenz]

Addendum: Enabling "Precache" the screen shows "Precaching" word forever with the music playing :p

[Smirftsch]

I've seen this error only if the card isn't supporting the OpenGL version fully. In other words, neither OpenGL3.3 nor OpenGL ES 3.0 are correctly supported by the drivers of this card as far I can tell.
