I don't really use it but my Dad has X-Plane (which I probably spend more time maintaining than he does flying!) and it seems like a very good and accurately modelled civilian flight sim.
To maintain reasonable fps (it doesn't really need to be more than 30fps) make sure you keep the Cloud Detail (Settings - Rendering Options) fairly low, probably 40% max, Texture Resolution on Very High and compress textures disabled, assuming you have at least 2GB VRAM (Extreme increases the VRAM load for no noticeable benefit and compression introduces some ugly artifacts), don't go crazy with the Stuff to Draw settings and make sure you have HDR Rendering enabled or else some lighting effects (particularly the night lights, runway lights) don't work properly.
Also, under Environment - Weather, set the Visibility to VFR (7 sm) although you might be OK with CAVOK (25 sm) depending on your system and be careful with the cloud type settings. Clear is obviously the least stressful and it increase with each setting up to Stratus.
There's some nice free scenery you can download that greatly enhances it as well:

The tricky bit is making sure the scenery loads in the correct order. It uses the scenery_packs.ini file in the Custom Scenery file for this but will just add new scenery you install to the top of the list, so you'll have to rearrange it as needed. It explains the correct order here

Here's what my Dad's file currently looks like, which I think is correct!

So it starts with the HD Mesh v2 scenery for all of Europe (at Zoom Level 17. You can save HDD space and download time by using ZL16 scenery if you're satisfied with that, or mix them up so that you only use ZL17 for specific areas). Then the OSM scenery for North America and Europe (this is basically roads, rivers, stuff like that). Then the photoscenery for specific cities, followed by the W2XP building scenery for specific cities and lastly, the Airport scenery.
As shown, you can use SCENERY_PACK_DISABLED to temporarily disable certain scenery, rather than moving it out of the folder, because if you do that X-Plane will delete it's line from the .ini next time it's launched.
