In my opinion, cockpit view on a flat screen is not realistic at all. There are features that other games offer that help but, when it comes to visibility, bonnet or bumper view are much closer to the visibility available in VR. In GTS specifically the lack of adjustable options for cockpit view render it as far from realism as chase cam. The ability to look around or "through" pillars and other obstacles can't be simulated properly on a single screen, at least in my experience in GTS, AC, and PCars. I can jump from VR to bumper without affecting lap times. I can't say the same for cockpit.
That being said, I do like cockpit cam, and it's what I use for most offline racing. The cockpits look so good it'd be a waste not to incorporate them into my playing experience. Also, as you have said, the varying levels of visibility between cars can only be replicated in cockpit view. However, even in cars with restrictive views, the outside views, rather than cockpit, offer visibility levels closer to VR.
First of all, you're wrong. Cockpit view does have adjustments in GTS, Assetto Corsa, F1 2016-8, and pCars 1/2, but even if it didn't, it would still be by far the most realistic option. Frankly, comparing anything to chase cam is ludicrous. There's nothing at all more unrealistic and ridiculous than using chase cam. There's no defense of, or anything even remotely legitimate about chase cam, so please drop the entirely nonsensical comparisons to that execrable chase camera view. I'll at least take your argument in favor of bumper and hood seriously, but the second you try to dignify chase camera like that makes it hard to take you seriously.
Honestly sounds like you've never used VR. The only difference between 2D cockpit view and VR is some peripheral vision, and depth perception. The loss of peripheral vision is somewhat compensated for by radar and left/right button assignments (not to mention bumper and hood have the same peripheral vision loss so basically you're arguing we should do ANOTHER unrealistic thing to make up for something that's already unrealistic). VR doesn't remove the cockpit entirely like hood/bumper camera does on a flat screen. The fact is, even in VR, your visibility in a closed cockpit is still greatly limited compared to 2D hood/chase/bumper cam and the added peripheral vision doesn't at all make up for it. Your lap times being the same supposedly proves that by the way. The only thing that is a major improvement is depth perception, but otherwise, your visibility is far more limited in VR compared to these insanely unrealistic hood/bumper camera views in GTS
The fact you use lap times to justify what's realistic and what's not is ridiculous. You're SUPPOSED to be slower without VR just based on the massively improved depth perception alone. The fact that you're supposedly not if you use bumper cam just disproves your idea that it's realistic. Lap times is only an argument against 2D bumper cam because they shouldn't be on par with VR considering VR's blatant advantages of better peripheral vision and significantly better depth perception (which frankly is far more important when it comes to racing). 2D bumper overcomes those advantages by giving you an unrealistic amount of visibility, which is exactly my point. It's entirely unrealistic to have more visibility in a sim than you would in real life, and that's why your lap times should be slower if you're not using VR.
Eitherway, it's absolutely ridiculous for a go kart to have the same visibility as a LMP prototype, and VR does just as good of a job proving why that's incredibly silly as playing on a flat screen does. If you tried both you'd see what I mean. In VR, your visibility from a kart, or even an open cockpit car is near limitless while in a LMP1, it's extremely limited, just like it is on 2D cockpit view and in real life. Those differences should not be ignored. 2 wrongs don't make a right. Losing only some peripheral vision doesn't justify removing the highly limited visibility of closed cockpit cars. The best compromise is not to do ANOTHER thing that's unrealistic like using bumper cam, the most realistic compromise is to limit the damage of slightly lost peripheral vision. That's what adjustable cockpit seats are for in GTS, and that's what being able to look left/right with a button press and the in game radar is for as well.
The only reason I think allowing VR in these competitions would solve this problem is because it's the only area PD actually forces realism so far by not letting you use other camera views. I think if given the choice between VR, and flat screen TV - hood camera, more pro players would still pick flat screens with hood/bumper camera which would prove that the peripheral vision argument against cockpit view isn't very relevant at all, besides the fact of individual car visibility being completely ignored with the alternatives. If the loss of peripheral vision isn't that relevant to them, it shouldn't be to you so I'm curious of what the pro's would choose after they've experienced both extensively, VR cockpit view, or flat screen bumper/hood. I have a feeling they'd chose flat screens, especially when it comes to racing prototypes. I have few doubts in that they'd prefer 2D bumper cam over VR cockpit when it comes to prototypes and if I am right, that would just further proof why bumper/hood/chase cam should not be allowed in a serious competition. It's too much of an unrealistic advantage.
Some of this is pure speculation of course on my part, so you're free to argue against why you think my estimation is wrong. I'm only going on a hunch and am curious what they would say given the options, and given that they'd actually experience VR for a good amount of time with multiple car types
Not to mention, the lower peripheral vision is why I tend to position the seat as far back as possible in cockpit view, giving me a better view of my surroundings than normal with cockpit view. Personally I think that's the most realistic way to do it because it reduces the limitations of using a 16:9 flat screen.
Frankly, even on a 4:3 screen, cockpit view is still by far the most realistic option. There's no excuse for open cockpit cars having the same visibility as a closed cockpit car in a sim, and there never will be.
I know it's a videogame and all. But no cockpit view in the elite GT competition. Feels just wrong
Again, I could not agree more. In fact, I think letting players use bumper/hood/chase camera is FAR more unrealistic and silly than letting players use controllers, so actually I kind of side with the OP in a way, just not with his overall arguments.
