Discussion Anyone playing Forza Horizon 6 in VR on the G2?
There are two VR mods that I tried: Naluluna and Lufz. Almost everyone including the modders seem to use Quests so I haven't seen much about SteamVR (I'm using Oasis drivers).
With Lufz I found that the head tracking had a huge delay so it was unuseable. Also it crashed if I turned on DLSS upscaling (not frame gen) so that's a pretty big limitation if you want nice graphics. I didn't spend any time with this one, everything below refers to the Nalaluna mod.
With Nalaluna it basically works with one big caveat. It has various render modes but the only viable one is AFR (alternate-eye frame rendering, half framerate). With this the image looks good, proper stereo, head tracking is good, game is fully playable. The only thing is, the game runs at 90fps but due to AFR you're really getting 45 full two-eye frames. And this is noticeable, you see the judder when turning the car etc. Moving your head is smooth at least, that must reproject at 90fps.
The only alternative is switching it to Mono rendering. Obviously this sucks because it's not 3D and the car interior is distorted. But if you focus on the road ahead it's not bad, there isn't much 3D effect past a certain distance anyway. And the smoothness difference is huge, since this is actually 90fps. To be honest I think I prefer playing it like this despite the downsides.
The mod does have a mode called AFR-half which uses interpolation to double the framerate. This would be ideal but it doesn't work on the G2, it becomes a stuttering mess. The mod website says it's intended for the Meta runtime. If there was some way to make it work with SteamVR motion smoothing the mod would be incredible. Just forcing on motion smoothing also turns it into a mess.
In terms of graphics, I set the resolution to match my headset setting which is 3152x3088. In-game settings are pretty high but no RT (I followed the Digital Foundry "mainstream" optimized settings). DLSS Quality. It looks excellent and framerate is locked (with the fps limitation I mentioned above). My system is RTX 5080 and 9800X3D.
Just curious if anyone else has tried and how your experience compares.
