Thoroughly enjoying PC3 for what it is and have no regrets in purchasing it and look forward to any updates in the future.
Improvements for me would be the AI as I personally will spend 99% of the time in the 'Custom Event' section of PC3 so I can race with any car and any track ( only because I am a Hardcore Sim Racer...lol)...at the moment on the AI's lowest settings they are still to fast...or maybe because I am slow...lol
Optimization would be great also as PC3 does not run or look as fantastic as PC2...PC3 is nearly their but have noticed especially doing screen shots I can not get the track in focus closest to the car I am photographing. When doing Rain screen shots I was unable to get the ground in focus even at 'f10' and 1/1000sec shutter speed to see the water drop rings sharply...this was just amazing in PC2.
Photo Mode is great, would like to see slightly more depth of field when zoomed in focusing on a car...more front to back focus of the car. Though I have tried PC2 Photo Mode on a Single monitor to test and there seems to be more depth of field using a single monitor, so maybe it's the Triple Screen set up that needs the DOF increase.
Audio is very much improved in PC3, personal opinion of course and although most of the cars I have personally driven sound fantastic I found the audio on the '69 Camaro' and '66 Mustang' a little low and muffled compared to others.
FFB / Physics of PC3 is great, now that I have dialed in my Thrustmaster TS XW...more than happy with the feel in PC3 for what this game is and is very much improved and consistent over PC2....oh, and absolutely love the 'FFB wheel tug' on my TSXW when changing through the gears...well done.
