5 years, and this is all still very relevant. The energy that he had to bundle and present all these and that too in a live audience!!

[zakparrish]

Sorry for talking at 900mph, folks! :)

[kaname]

Super informative talk! I am currently optimizing my game and trying to find more bottlenecks for it. Loved it!

Just profiling our project on 4.27: definitly one of the best video out there. Usefull, rich of contents and straight to the point.

[chronnodev]

Simply the best profiling video for UE4 out there - thanks Zak!

[aysikl]

congratulations! that's one of the four lights

"I wrote it like that due to it being a captain obvious type of thing that happens quite often, I don't mean to be snarky at all it just felt like a good way to communicate this point"

that'd been kickbutt :p

[reaktorleak]

I actually came here after watching a ton of Digital Foundry videos. Feels extra relevant since I'm making a racing game in Unreal.

[makanansari]

Oh Zak, always keeping the good work! I had so much fun with your UDK tutorial series! :)

[misha_lunyov]

feeling myself like Neo after his first study practices in simulation.... thanks :D
- i know ue4!
- show me..

[issacdhan]

This video is exactly what I was looking for. Really very important and informative.

[SirToxe]

You know you are in for a great video if it says Zak Parrish in the description. :-)

[mhnoni]

Really informative, the only part i didn't get was when you talked about Hard references in BP which slow FPS down "when you load a BP every other BP it referenced must be loaded" hope you can expand this line more with 3rd person character example let us say.

[NixCM]

Great talk, thanks for emphasising Event tick! I honestly had no idea!

[cumuIonimbus]

"1 or 2 people ever used Blueprints in this room..." - EXACTLY, you should do much more tutorials about the dark side which is C++.

[KPanic]

Thank you so much for posting these videos, they are gold!

[aysikl]

avoid casting operations

I'll cut you this deal, epic... if y'all start making tutorials where you don't push everything into level blueprint and use casttoplayer and stuff ALL THE TIME YOURSELVES
then friendly ned flanders says okily dokily.... :p

[Pavel-nqpc]

Thank you for this helpful video. Is it possible to get PDF version of this presentation ?

[blackarrowprojections]

2:28 "By the way, I just want to mention that this is a room full of game developers and your all here before 11am....give yourselves a round of

Finally....permission to not feel guilty about our way of life....

[myboydutch]

HLOD requires Simplygon? I thought that was only for automated mesh triangle reduction? The HLOD docs don't even mention Simplygon at all.

[juanmilanese]

You Rock Zak!
Any chance on having you making tutorial series for this channel again?
