Given our first round of testing, I really wasn't sure what to think and thought it would be minimal at best. After full review of the numbers, it's clear that some weather effects really impact your performance. If you want/need performance bump, it's as simple as disabling your weather or just keeping the default. If you want to have some additional weather effects, try using Ash, Snow, Pestilence or Aurora. You will have some impact by using those listed, it should minimize the impact to your gaming experience.

Hope this information was helpful and provides a positive impact to your gaming experience. Until next time, good luck with that MMR grind!
