New issue: GP Bikes on Steam, running Virtual Desktop (on Oculus Quest 2) and Steam VR crashes on startup for me.
If I don't start Steam VR before launching, then it works fine. If Steam VR is already running, then it crashes. If it is running and I exit manually before launching, then it works.

MX Bikes works fine regardless of whether Steam VR is already running.

Not a huge issue since I can work around it. And I don't know if my repro will work on other machines.

But also: Thank you for both MX Bikes and GP Bikes. Both are great!

Yup, will do. My previous laptop didn't have an integrated GPU, so I'm noob at this.
I have seen that setting, but it says 'Windows OS now manages selection of the graphics processor', so I figured it was being deprecated.
Thanks!

Yeah, sorry - I should have tested that myself before posting (doing so has not helped with other games). But it did help here. Both GP Bikes and Kart Racing Pro now work! Thanks!

Sorry for spamming here, but here's the same log file from the MX Bikes folder (and MX Bikes works).

Found the log file. Attaching it.
I guess it looks like it's trying to use the integrated gpu. Which is not going to work well.

GP Bikes VR crashes on startup on my new laptop (Ryzen 5900HX, NVidia 3080 Laptop).
Kart Racing Pro, Oculus, also crashes on startup.
Kart Racing Pro, Steam-VR, runs fine - but only displays the view on the main screen - not the goggles (hdmi port).
Luckily, MX Bikes works perfectly - both Oculus and Steam-VR. Maybe some VR startup code could be copied or integrated from there?

I don't particularly fault PiBoSo, because even the Oculus App itself has problems. It states that my "computer doesn't meet the updated minimum specifications". I wonder if it's basing that off the integrated gpu. Many other apps have issues, but most high profile (VR) games work fine.

Model: ROG Zephyrus Duo 15 SE GX551QS-HB109R

I have nothing important to say - I just want to praise GP-Bikes VR a bit.

I think there is no other category of game that is enhanced as much by VR. You get enhanced depth perception etc, which helps making breaking more consistent. The thrill of being so close to the ground at such high speeds is unparalleled. And determining the correct angle to lean and the correct speed to take corners just becomes so intuitive (I use tilt 50% and lock-to-bike disabled).

I'm no bike-game person by any means (or bike-person either for that matter), but I have tried a bunch of other ones recently (Ride 4, MotoGP, TT Isle of Man II etc). Although I also really like Isle Of Man games, I think physics in GPBikes - with VR in particular - is still a couple of notches more plausible and intuitive (it takes a while before you get the hang of it, of course, but once you do, it feels like second nature).

It's weird, but despite not being much of a game per se, GP-Bikes is up there with my top VR games ever - maybe the best ever (I've played more than 100 VR games). MX-Bikes is cool too - but not quite at the same level IMO.

Anyway: nice work! Hope you make a steam version eventually.

Yeah, when in mode 0 ('lock to bike', I assume), when the bike itself wobbles, it's pretty uncomfortable in VR. I don't think it's very realistic either, since your head in real life wouldn't follow the bike like that.

Mode 1 is mostly fine. As you say, the jitter is almost inperciptible at higher speeds.

I only discovered GP-Bikes now, and I really like it.
I've been really curious if VR would work with a motorbike game - if it would be too weird with the view following - and perhaps even tilting - with the bike.

I'm now 100% certain that it's possible. GP-Bikes almost works IMO. I'm totally fine with the view tilting with the bike. But the sideway 'wobbles' don't feel good.

I also tried mode 1. It's better, but then there's a sideways jitter at low speeds instead. It almost feels like a numeric differentiation precision issue.

Anyway, I mainly wanted to say that I greatly appreciate what's already there.
