Re: can a surface pro 9 play sims 4 at its best settings?
@SuperNTG Upgrading to 32 GB RAM shouldn't have any effect on how Sims 4 runs. If the game's using more than about 8 GB, it's because of a problem that's likely going to cause a freeze or crash on any system. And your other background tasks shouldn't use enough memory for the computer to run out either.
The upgrade to an i7 would improve performance, but not by a large margin. It's difficult to say precisely how big the gap would be because I can't run my own tests, but it would probably be about 5-10% based on the relative performance of the two graphics chips in other games. If it's a cheap upgrade (when separated from the extra RAM), it's worth considering. But it's certainly not necessary for Sims 4.
