ID tech 7 is an absolute behemoth of engine. Coupled with the wizardry of ID Software, im excited to see what's next. The fact it runs a flawless 120fps on Series S is a testament to its adaptability.

[HueyTheDoctor]

I love how Billy names and acknowledges the specific people who worked so hard to implement the features being discussed. They're all legends.

[SaimizZ]

You guys put him onto a monitor from the game LMFAO

[DONE]

Easily one of the top 5 most impressive engines that I’ve seen. They’re able to produce some amazing stuff.

[svartholstjornuson]

I love how his screen is ingame. Awesome interview, you two. Thank you, John, for putting this together.

[piyh]

I like how developers are taking DF into account when developing games now

[jjforcebreaker]

Great! More dev (behind the scenes guys, not PR people) interviews please!

[Panyc]

iD, The Coalition and Asobo are so talented. The way these teams push the tech is always fascinating.

[beakerbkr]

This has been such an informative interview. Thank you, Digital Foundry, for giving voice to the typically unheard heroes in game production! I'm sure the individuals on the visual presentation teams love the opportunity to dive into the results of their hard work!

[AlphaDwg]

i love the fact that you can toggle graphic settings. Thank you for putting in the work to make it possible.

[calebduke]

I’m super impressed with the close collaboration with the art team. That’s exactly how this type of thing should be done.

[thingsiplay]

"Make it artist driven, not technology driven."
I wish more companies would design and create games like that.

[AlexandruTataru]

Such a lovely interview. This guy is passion for profession materialized and he speaks very nicely about the team and the great work everyone did. I enjoyed every minute of the interview, both the chat and also the technology aspects. Keep up the good work DF and best of luck to the id Software guys, looking forward to new games from them.

[Taijifufu]

Love hearing from the devs what led them to make specific design choices. Looking forward to id's next project.

[willwunsche]

These guys have become some of my favorite developers. Amazing game; amazing performance; caring enough to put effort into the Switch version, ray tracing and cool features; listening/caring about other departments; they genuinely seem like they want to make the best game possible; and their wholesome reaction to the Doom Eternal speedrun. I hope they continue to try and outdo themselves

[AHXX]

DOPE ASS INTERVIEW!! ID tech are definitely masterclass developers!!

[BillyBetYT]

Doom Eternal was my GOTY and remains the best shooter I’ve played in a decade.

[HBObiWan]

Thanks John and big thanks to Billy for this tech talk. I love these and seriously miss the Carmack talks from Quakecon. Feel free to make them much longer.. just saying.. :)

[liaminwales]

It's just amazing to see ID tech back as a god of games, amazing work!
So happy you managed to get an interview, I may not understand it all but just happy to get to hear it.
