Unreal Engine Code Issues Fixed By Third-party Company

An anonymous reader writes: Unreal Engine is the famous game engine that was used to implement such games as Unreal Tournament, BioShock Infinite, Mass Effect and many more. On March 19, 2014 Unreal Engine 4 was made publicly available from a GitHub repository. It was a big event for the game development industry. One of the companies that took an interest in this was PVS-Studio, who created a static C/C++ code analyzer. They analyzed the Unreal Engine source code and reported to Epic Games's development team about the problems they found. Epic suggested a partnership with PVS-Studio to fix those bugs, and their challenge was accepted. Now, PVS-Studio shares their experience in fixing code issues and merging corrected code with new updates in a major project that shares its source code.

Why do I feel like this is an ad for the code analyzer?

I believe you didn't read the link. It was written by PVS staff, and states very clearly that the effort was to promote their product:

As a way of promoting our PVS-Studio static code analyzer, we've thought of an interesting format for our articles: We analyze open-source projects and write about the bugs we manage to find there.

They made it to Slashdot, so the effort was a success on some level. And maybe more people need to be aware of code analyzers (we just enforce code conventions and obvious bad practices).

Re:Problems causing Video effects?

The big question for me is do coding errors affect video rendering issues?

Sure. Just remember that the video driver is a whole bunch of code. It's code all the way down.

A long time ago, I set up Siege of Avalon (at that point, already a 5 year-old game) and, upon getting to some specific level, found that performance had gone down the toilet. I fiddled around for a while, then (for some reason) called the support number. They told me to update my video card drivers. I told them that the video card drivers were already about 4.5 years newer than the game itself, and so their suggestion made no sense. We debated for a while, but they stuck to their guns. I hung up, frustrated.

Updating my video card drivers fixed the issue.
