To each their own. 60fps imo is already a visual improvement, although it doesn't show in the shaders, it shows in clarity. A big part of why people are amazed by the graphics of 30fps (ontop of having more render time), is that the brain is doing a lot of work on interpreting the image. That motion blur really makes details hard to see, and your brain is left to just say if things look 'correct'. And DC had some pretty close to correct lighting, too dark for my tastes, most of the overcast levels should have had day time running lights at the very least, I felt the game feels like it's driving in the dark to create the hyperrealism of it's lighting of the game.
But when you play a high FPS game, the image is exceptionally sharper, and as a result, you see a lot more flaws and it becomes much easier to criticize the game.
But heres the crazy thing, have you ever jumped from a 144fps games (plus monitor refresh) and dropped all the way to 30fps? Your brain has such a hard time recalibrating, I thought I was watching a slide show for 3 minutes until my brain readjusted.
Things look actually _darker_ because of low refresh. I found this out the hard way, when I started playing sc2 on my 144 gsync monitor, but the refresh was capped to 30. scrolling around the map, everything looked like it was flashing. Obvsiuoly this doesn't happen on TV, there is a built in refresh to refresh content regardless of input, but once I pushed to 144 refresh, everything was like looking at a screen shot. You don't miss any detail, and all the colours come through, ghosting goes away. And I think, if I were to be critical, and why I like GTS, is because that move to 60fps, yea, it's more flawed, but it hella sharper, and much more enjoyable to drive and watch. Its less exhausting overall (I hate the constant overcast/night time shit), I like to race in daytime, it looks great to me.
GTS doesn't come across as sharp in terms of image quality as F7. But it has some really nice lighting as their trade off, something I hope F7 will get to one day.
