I'm enjoying it. I bought the base game in the PSN sale when they announced VR support. I gave up on the cockpit camera almost straight away and switched to the bumper cam, as I prefer to have my view filled with the road, rather than lose a load of screen space to the cockpit.
I've been playing VR using the same bumper cam (though it needs to be enabled in HUD options for some reason) and it's much easier to read corners. It does feel like you're really close to the road surface, and if you get close to trackside plants they look flat and low resolution. The fade-to-black is too keen to kick in when you make a mistake and can't be disabled, AFAIK.
It's a good VR mode, but whether it's worth the money or not depends on how much you like rally sims. It's a tough game with a steep learning curve. I've always liked watching Rally and being able to drive Mk2 Escorts and Lancia Deltas brings a bit of nostalgia to it.
I love it, I'm reading how some people don't like the 'black closing eyes filter' that kicks in when you go off track. Personally I don't mind it because I don't crash that often but when I do its usually in spectacular fashion and I'm barrel rolling into a tree or some such. So yeah the filter doesn't bother me and wouldn't prevent me from recommending this.
Its genuinely amazing and you will be able to take corners in a more natural fashion. I was worried about motion sickness with this one before going in, but I was fine. I recommend short breaks between events though as its pretty intense and the rally stages can go for 8+ minutes sometimes. For reference its the only way I've been playing the game since its release. Oh and for the upgrade price your getting a full game VR conversion all cars and all tracks, not just a separate VR mode.
(My experience is based on Pro+PSVR)
I decided to take the plunge based on your impressions... I'm very satisfied! I don't know if it's just the perspective from the cockpit or what, but I do feel like the steering model is different in VR. I was much more in control of my car and making tough turns one after another without a lot of trouble. Certainly nowhere near as much grief as the game gives me on-TV. I'm probably going to always play it in VR now. $13 well spent. So thank you for the recommendations!
I did encounter an issue with getting the upgrade to install/work. My wife was playing something on PSVR while I queued it up from the web store on my phone, and when I went to tap "Download to my PS4," it just hung (the loading indicator). I tried it several times to no avail.
After that, I asked her if I could check something really quick, and when I went into the PlayStation VR menu for the game, it still had the "Buy" button. When I pressed X on it to proceed to the purchase screen, it said "Purchased." I tried restarting the game a few times, toggling the PSVR headset on and off, etc., nothing worked. What finally worked was restarting my PS4 completely from the Power Settings menu.
Also, anyone else really psyched about Psychonauts in the Rhombus of Ruin on Tuesday?
