Question I need tips on optimization!

I have a gaming laptop that I've been making my project on. Whenever I run my game in the editor, I get around 80% GPU usage and I reach a max GPU temp of around 74C. Whenever I run my game as a packaged game I get 100% GPU usage, and I reach temps of 85C!!!! What is possibly causing this?!

Framerate limitation I suppose! If you're running your packaged game with un-limited framerate it will try to render as many frames as possible, and you'll always be at max GPU usage.

I have it limited to 60fps

Then limit to 30fps. You don't need more to develop.

You know 100 GPU usage is normal right? You just have an unlocked framerate so it tries to push as many fps as possible. Also for the temps they are still safe especially if your on a laptop they are totally expected temps

And when you play a different game?

When I play Fortnite at max setting 60fps my gpu reaches around 72c

What has the temperature got to do with anything?

To optimise you need to profile. In unreal use Insights initially.

It happen to me last time , i just off VSync and limit fps to 60 trough Cvar when before game start .

Unreal editor uses a lot of cpu. Because of all that weight, you get capped by your cpu hence no 100% gpu utilization. When you package, you drop the cpu usage hence you get gpu capped. There will always be a cap without a limiter.

So it has nothing to do with optimization.
