Sim Update 5 performance before and after

I am guessing you are constrained by vsinc, disable it both in options and in NVCP (near the bottom), if you get tearing set max fps in the latter to your monitor’s refresh rate. You should then push your LOD all the way up to and even past 200 by using the .cfg hack (until Asobo make the higher LODs available) and then adjust your other settings to suit. Oh and do set your gpu to 100% renderscale first, this was a performance update afterall. Tweaking it back is most likely the last setting you will make and it can be used for extra stability over cities etc.

Don’t forget Babu’s revised tuning tips, don’t be mistaken by the date, it is in the US m/d/y format
