Hi folks, This is my first post in the dev talk forums, I’m not a developer (not yet anyway :) just a computer science major.
Anyway, my PC is struggling with Z-buffer fighting in many of the video games that I play. From wiki: “Z-fighting is a phenomenon in 3D rendering that occurs when two or more primitives have similar values in the z-buffer.” The resulting effect is a very annoying flicker caused by the two polygons “fighting” to be displayed
I’ve found lots of good videos from youtube to demonstrate the problem:
Fallout New Vegas:
Skyrim:
Battlefield 3:
I’ve also seen Z-buffer fighting in:
-The walking dead (the video game)
-Star Wars The old Republic
-Burnout Paradise City
-Crysis 2
In fact there’s even an entire web page built for people struggling with this:
Here’s my current specs:
CPU: Phenom II X4 960T
Mobo: A770E3
RAM: 2X 4GB Corsair Vengence @ 1333
OS: Win 7 pro 64 bit
GPU: Nvidia Quadro 4000D
Here’s what I’ve tried:
- Switching GPU to HD 6850 and HD 4870
- Switching GPU into completely different computer
- Reformatting/reinstalling windows
- Upgrading Power Supply + Computer Monitor
- Applying Game updates
- Applying GPU driver updates
- Applying Mobo bios updates
- Applying Mobo chipset updates
- Contacting Game manufacture
- Contacting GPU vendor
- Contacting AMD support
- Contacting Nvidia support
- Extensive Forum research
Please escalate this post, I really need an expert. As I said, many tech savvy people have thrown up their hands at this one. It’ll take a hardware genius to fix this one.
$$$$You want to know the real truth?.. I’d never buy a Radeon card if it meant not having the flicker (and I know many who would feel that way too)… But as it stands, both AMD and Nvidia struggle with this.$$$$
Please help.
