Oakmont is not ready and either is this site.
It might be ok in single play, but I just played two 9's in match play challenge and the loading was so slow it took 1 hour and 45 minutes per 9 holes....only to time out both rounds ...2nd round was timed out on the first playoff hole after an unbelievably brutally slow round that I just wanted to end. The match ended due to a timeout issue that I couldn't recover from in the 5 minutes they allow you. That was nice to have it end that way in a playoff after suffering through almost 2 hours of brutaltity. I was already was not happy with this horrible site after not being able to log in for over two weeks due to some network glitch where a lot of people could not log in.
I am finally able to log in and actually get to play the back 9 to St. Andrews for the first time....and now Oakmont....only to find out this site site is even slower and has more meter glitches than I remember.
I'll check back in a few months and see if there is any more improvement on the playability.....that should be the WGT's top concern. They have a very long way to go.
There is a reason this is "STILL" considered beta mode.
