Just curious:  As a new adopter of Prepar3Dv4 (moved from FSX a few days ago), I wondered whether things like HighMem fix, Affinity Mask, or even using Nvidia Inspector were even necessary for this program.  I would appreciate hearing your opinions on this.

None of them is required and I would strongly suggest starting without any of these (or any other) tweaks.

Highmem has been repaired in Prepar3d1 already. I would start without even an Affinity Mask, notably if you are running with HT off (I have HT on Core 1 off via SimStarter giving Core 0 a bit more headroom, but the observable difference is minimum). Nvidia Inspector was required for Prepar3d until version 3, but LM vastly improved Antialiasing for version 4, thus I'd suggest choosing a higher in-game value and forget about NI. I use the highest setting, but for a weaker Graphics Adapter you may have to opt for a lower setting.

Kind regards, Michael 

I do not use any tweaks at all. Runs just fine as it is

 

Same here, came over from FSX to v4.  Spent too much time fiddling with cfg files in FSX I've just left it all alone for P3D.  I only use the settings built into the sim itself.

Me too, looks phenomenal and flies like dream. In Sim changes only with the exception of Desktop Nvidia Control Panel which uses only the Preview option set to Quality.

Exactly the same advice as the others. I just crank up most everything to the right and fly in dreamland...

I've not felt the need to tweak anything in P3D, LM did all that already. The very fact that you've bailed on FSX because it needed tweaking, to a platform which doesn't really need those tweaks means you can spend more time flying and less time worrying about that stuff. If it ain't broke, don't fix it.

As an also-new adopter of P3Dv4, I have not tweaked or done anything. Runs fine out-of-the-box.
