Silent FPS drain hiding in plain sight

'Camera.main' looks like a simple property access, but it is not. It makes the full scene search. Every. Single. Frame.

This exact issue was found in an open-source Unity project, SanAndreasUnity. Sitting quietly inside 'LateUpdate()', running on every frame, this little boi is doing far more work than developers may have planned.

If you're writing Unity code, there's a decent chance something like this is in your project right now.

Want to know how to boost the performance of your game dev project? Don't you know what triggers FPS drops? Good time to change the game.

Our free webinar on June 2nd covers real bugs like this one — where they come from, how to find them before your players do, and which tools actually help.

Hey followers! Do you know any open-source C++ projects built with AI? Drop them below in the comments
We'd love to check them with PVS-Studio!

To keep PVS-Studio sharp against whatever new patterns of bugs vibe coding introduces, I′ve been hunting for real open-source C++ projects built this way. Turns out finding them is the hard part.

AI agents aren't coming, they already inhabit modern codebases.

But what errors can they bring in your Golang code? We’ll explore this topic in our new article.

Today, almost everyone has got a taste of the vibe code, and some have gone a step further by setting up their own AI agents for projects. Meanwhile, headlines are buzzing about how some AI agents...

Smart pointers don't fully save you from dangling references and PVS-Studio have a proof:

V758 The 'graph' reference becomes invalid when smart pointer returned by a function is destroyed.

'create' returns a smart pointer to the 'FlannNeighborhoodGraphImpl' type, and its object reference count is one.

'graph' is created for the value of this smart pointer while the object reference count remains unchanged. But the pointer is a temporary and goes out of scope immediately after that line. Ref points to a destroyed object. 'for' references invalid. Result: undefined behavior.

How to fix? Keep the smart pointer so that the 'FlannNeighborhoodGraph' object stays until the end of the block and limit the 'graph' visibility area.

We've already reported the bug to the developers and created an issue: https://github.com/opencv/opencv/issues/28167
(And some of bugs already fixed, you can check the last OpenCV release notes)
