469b- bizarre graphical bug with XOpenGL

Post by Mantha065 »

I've played 50+ hours using 469b running XOpenGL renderer, and I've never had this issue until now:
Happens on all maps. Anyone else had this/anybody know what to do to fix this?

Make sure you grab the XOpenGlFix from anth on the discord. He posted a link to it.

I'm gonna piggy back this thread since I'm also having issues with XOpenGL.

As you can see, the weapon models are bleeding through the hud. This happens at an FOV over 96. Is there a fix for this as well?

I'm using a GEForce GTX 1650 Ventus XS GPU, AMD 3900X CPU, UT99 Patched to v469b, 1080p res.

(I was also having issues with disappearing weapons so thanks for sharing those updated XOpenGL files! They didn't fix this though lol)

Pretty sure you have to enable ZRangeHack in your xOpenGL settings.

Type preferences in console(if on windows), go to the XopenGl section and enable it. If you can't find it open UnrealTournament.ini in your UT system folder(with game closed), and add ZRangeHack=True at the bottom of the [XOpenGLRenderDevice] block.


ZRangeHack - [True/False]
An experimental option that can make the z-buffer work better for far away objects. Might cause unexpected problems, but doesn't seem to break anything major so far. Will fix problems with decals flickering in the distance with 24-bit z-buffers, which is the most you can get on many video cards. Will also fix the issue with the Redeemer covering up part of the HUD. Partially breaks weapon rendering on the first person view one if using wireframe debug mode (will clip near parts of it). Doesn't help enough to make 16-bit z-buffers work correctly.

Thanks for the response. Unfortunately, that did not seem to resolve the problem. bio, flak, mini and redeemer still block out part of the HUD for me.

Unless you're testing it for development purposes, don't use XOpenGL. It's significantly less performant than either of the popular old cwdonahl renderers, and as you've discovered, it has bugs that can interfere with basic gameplay.

AFAIK there are no extra features XOGL enables. It's basically just a worse, buggy renderer. I know the 'X' in its name makes it sound exciting, but it really isn't. Let the beta testers worry about it.

XOpenGL isn't meant for any PC, just PCs with graphic cards or circuits that support OpenGL 3.3 or more. For everything else you either use regular CWD OpenGL or any version of DirectX your system supports.

ProTip 2: anybody who uses the "Royal We" when making a demand wants to pass their own opinion as everyone else's.
ProTip 3: Only the people that do nothing but criticize don't make mistakes. Do things. Make mistakes. Learn from them. And screw those who do nothing but throw poison and criticize.
ProTip 4: If the Duke Nukem Forever fiasco wasn't enough of a lesson, perfectionism leads to nothing positive. Don't be afraid of releasing a buggy product. Even the most polished product has its flaws.

I don't remember all the details but wasn't xopenGL made in mind to make the game appear similar to what the developers intended to have it look like back in 1999?

It is just "OldUnreal's latest OpenGL 4-based 3d renderer (XOpenGLDrv)".

AFAIK it is attempt make driver which aware of latest OpenGL possibility and supported modern hardware.
