Have you ever wanted to play TDM in VR? Now you can!
Phew, it's almost exactly been 3 years since my first post about my VR modification for TDM. Three more versions of the game have been released in the meantime, and with them come performance improvements that I feel it's finally viable to continue my work on the VR adaptation
Grab the latest release! It's based on the future 2.09 version, but is fully compatible with a 2.08 install.
Although I've tried to make the VR version use its own set of resources (separate `darkmod_vr.cfg` and shader folders), I'd recommend you make a backup or copy of your TDM installation to be able to get back to the flat version cleanly without effort. Please heed the README in the repository, particularly about the choices of VR backends.
Some noteworthy information for this new version:
- performance should be considerably improved from the old alphas. That doesn't mean it's perfect - although the CPU bottleneck is now completely gone, the game is now severely fill-rate limited. So if you have a current-gen headset with high resolution and/or a weaker video card, forget about any supersampling or AA. I also strongly recommend to stick to stencil shadows and disable soft shadows and ambient occlusion - the latter isn't that impressive in VR, anyway, and simply not worth the GPU cost. And even then, there will be some scenes in some missions where reprojection is just unavoidable, even with the beefiest GPU. That being said, I have tried a multitude of maps, and I think it's very playable.
- the UI is finally usable! Both the menu and ingame HUD elements are projected to a virtual screen in front of your sitting position. It's not the most elegant or immersive solution for the HUD, but it works
- vertical mouse movement is excluded from the VR view - this was suggested by some of you way back, and I think it makes the experience much more enjoyable. It can make it a little hard, though, to aim with the mouse for actions like frobbing items, because there's currently no visual indication to where the mouse is pointing. I'm planning to add one asap, but in the meantime, you can equip a weapon to get a vague sense of your mouse orientation. If you do want to re-enable vertical movement in the view, set 'vr_lockMousePitch' to 0 in the console.
Other than that, I hope you enjoy this new version. Let me know which improvements you'd like me to work on first. Also, there are probably any number of render and other bugs still left in there somewhere. If you find one, please report them over at the Github tracker (Github.com), so I can keep track of them
