Yeah, I know a lot of people say that, but there are definitely issues with Skyrim without PP. There are problems with shadows, and occasionally with lighting, especially as the objects in question get closer to the edge of vision. Then there is the water issue as well (very slight mismatch between where the water should be and actually IS, only at certain angles). I will say they are very minor, enough to the point that many don’t even notice them, and I’ve often tried to get used to them as Skyrim VR’s performance without PP is indeed fantastic. Unfortunately for me I’m one of those people who notices things like this immediately and I just can’t un-notice them. The instant a shadow isn’t laying at the correct depth (bridge into Riverwood has this issues quite noticeably) or a light-source isn’t right all my attention is drawn to it. I’m also one of those people who absolutely can’t stand watching 4x3 video incorrectly stretched to 16x9 (poorly setup sports bars, anyone, anyone?) and I’ve seriously sat there and talked with people who literally can’t even see the problem. I don’t mean they are ignoring it or don’t care, they actually can’t tell that everything on the screen is in the incorrect aspect ratio. They can’t see it. Weird. I can also tell, instantly, if I’ve accidentally walked into a movie theatre that’s still using those old 2K digital projectors. So, so blurry.
I’ve tried everything I can think of to test if the problem with PP<->Motion Smoothing is on my end, short of swapping in a completely clean boot drive for testing purposes. I suppose, maybe, it’s a three-way incompatibility between current Nvidia drivers and PP+Motion smoothing. That’s getting really hard to test for at that point though.
Definitely was not an issue with earlier versions of Pitool, but realistically several things have been upgraded in relatively short order. Still, everything else works just like it should, it’s just those two setting, when applied together, that create the issue (hence my initial thought that it’s a Pitool issue).
