Is there a way to downgrade to a previous version

After my most recent update I my simulator is extremely laggy and I would like to downgrade as it was working fine before. I also know its not my computer as I have an xps 15 with 16gig ram and it runs fine on other programs that are more intensive.

yeah, i have got the same expirience. I don’t get more than 4fps when scrolling over a 1 minute chart and so on. Is there a way to fix that?
