To verify the issue (meter skips, jumpy graphics, etc) is not my pc, I downloaded wgt to my new windows 10 laptop, expecting better performance.
That's not what I got. Same jerky graphics, screen freezes, meter skipping like a mad dog after a rat. Unplayable, to say the least.
Conclusion? It's not the hardware we have. The game played very well prior to the Nov update. Hopefully wgt will correct this, otherwise many will find other methods of entertainment.
Good luck to all,
cheers.
