A few friends and I are now organizing our own graphics programming conference in Europe: https://www.graphicsprogrammingconference.nl/
Think: Game/realtime graphics, rendering, just in Europe, with less flying and cheaper hotels, to meet the same folks you'd meet in San Francisco otherwise :)
If you're interested to speak (and want to submit a talk), reach out to the contact email provided there or DM me. Same for sponsorship opportunities.
Retoots/boosts are appreciated!
