the sound at 15:46 is absolutely insane
-
Engine go vroom vroom am I right 😁
-
17:41 POV: You lost GPS acces and went too far off into the texan countryside when you hear a tuned tracker from behind start to overtake you lmao
-
that wobble sounds perfectly reasonable and realistic, it's probably a bad exhaust design and not a simulation issue
-
Holyyyyy the pull at 15:46 gave me chills
-
Hell yeah, man's been cooking.
-
The trick to having multiple things operating on a single state is to double-buffer it so that CPU is reading from previous frame's output, and GPU is rendering with it, while CPU (or whatever device is performing the simulation step) outputs the simulation increment to a back buffer. Then you swap the buffers' roles. I'm sure you're well aware of double buffering, but sometimes we forget things!
-
Everyone is saying this, and i'll say it again, the sound at 15:46 is CRAZY. I cant wait for more updates, this is looking incredible.
-
I was one of the people who was a little disappointed at the single cylinder sound. This completely obliterated any concerns I had back then. Honestly this already sounds absolutely amazing, especially the comparison with the unprocessed sound from ES2D shows how far this project has come. This completely restored my faith and I will worship at the altar of Tubular until this gets released!
-
17:43 straight up sounds like a tractor to me
-
oh dude, the audio is sounding so awesome now! Your progress feels hard earned, and is showing fantastic results
-
18:50 You taking shots at Honda owners haha.
-
19:20 actually sounds like my miata with the muffler delete
-
ES3D sounds so much better than 2D, I cannot wait until I can play with this
-
If I'm not mistaken, the wobbling you spoke about at 15:46 is a result of exhaust air resonating in the system. I think that sound happens irl too with some exhaust systems. You'll of course want to check and verify but if it is because of a physical property and not an issue with the sim, it means you're doing very good with the exhaust side of the simulation
-
The old simulator sounds like an electric toy in comparison, whereas if you close your eyes, you're absolutely riding that bike with the new simulator. Very well done.
-
15:45 Jesus christ this sound is insane! I think I just had a eargasm
-
The fact that this is absolutely pure output of the simulation and that it sounds so real is astonishing
-
I had no idea anyone complained about the new version sounding less realistic, and I'm giggling now because OF COURSE it initially sounded less realistic, it was really early in development. It's STILL really early but SO GOOD.
