I found a fix for the lag spikes I was having. This puzzles me because I have a top tier 1070 Nvidia video card as well as a really top dog computer system. I will add this lag spike issue only happened with the 9.17.1 update. I ran on the highest graphics settings before the update.
The fix is set the graphics settings to "Custom" and details to "Standard", turn down some of the graphics settings. NO MORE LAG SPIKES!!! YAAA!
Why do you consider this a solution when the game was working for you pre-patch? Gimping your graphics settings just to get it to run is simply giving up and allowing WG to provide a sub-par experience compared to the way it was working. They need to step up and admit there's an issue with the micro-patch.
