Using engine statistics, you will get editor overhead whilst doing that so it'll generally be slower than it would be in a build. As for fraps, well not a clue what it does but it doesn't seem very accurate.. @GarBenjamin In terms of graphics, Unity doesn't worry me.. There's plenty of asset store stuff, I only need it to look as good as Witcher 3 for example which I can't think of a good enough reason why I couldn't. Secondly it has middleware like Umbra which in games like these is invaluable. I could easily make the game in Unity and have relatively no issues at all (even if it would be 10X the amount of work)... Although I'll be open about it for once, the reason I'm trying to do everything else under the sun is because I'm angry at Unity. They strung me along for about eight months at the time of Unity 5.X's release promising it would fix all the issues, so I was like sure.. Keep working with the editor crashing every ten minutes or so until they get it out the door. I'm the muppet for believing them I guess? By the time it actually got it's half baked debut, I'd had enough.. Reason I don't use Unity is out of principle and nothing else, I didn't even get anything in the way of an apology. I might have to swallow my pride, but it's not something I'll forget any time soon. Again, I've not a problem with the engine.. But I do have a problem with Unity themselves.! Every piece of news I hear from them lately just compounds that feeling, they want to charge more but they can't justify it in relation to their competition. It's one silly decision after the next.. What I should pay more for an inferior product? In terms of rendering performance, UE is better at it "generally" but you're stuck with the inherent issues with some of the choices they made. Which makes specific games slightly problematic dependant on your target group..! Yes on medium settings it does look far worse than Unity does.
