Hi! To put it short, I use a lot of Irish scenery as I am Irish and personally like Irish flying. I also have quite a few aircraft too. Only problem is, FPS is being compromised and I fear that unless I get advice for my specific PC specs, I will have to fly with minimal detail settings. Here are my specs to give you an idea. I see many guides online but I wonder whether they work for mine or not. Loading terrain data holds at 6% for about a minute before then jumping up to 69% for like 40-45 seconds, goes from 70%-83% in about 7 seconds, holds at 83% for about 25 seconds, then 92% for 20 seconds before slowly going up to 100% in 5 seconds. Takes around 3 1/2 minutes on first boot.

 

Graphics Card: NVidia RTX 2060 Super

Processor: AMD Ryzen 5 4500 6-Core (I have hyperthreading enabled so there are 12 logical cores)

RAM (If needed) 16.0 GB (15.8 GB usable)

PC (Also only if needed) Windows 11 Home

Kingston SN2VS1000G

 

Any further specs required and I will give them. I also ask for your help because I plan on getting  ORBX's Ireland scenery soon and I don't want to mess up my FSX with endless lags to an unplayable state.

EDIT: PLEASE DO NOT RESPOND TO THIS AS I HAVE FOUND A FIX FOR THIS!

Follow the advice in the Avsim FSX Configuration Guide to the letter and you won't go too far wrong.

When I first installed FSX in my currrent computer I used all sorts of recommended tweaks over a period of time to try to get it to work smoothly - not a good plan! to cut a long story short, I eventually ended up doing a fresh reinstall of FSX but the second time I precisely followed the advice given in the Avsim guide and I have happily had a generally smoothly functioning FSX running on my pretty old PC for years! Mine does however also take between 3 and 5 minutes to boot depending on what scenery is active so your 3 1/2 minutes startup time doesn't sound too bad!

Be aware though that the combination of resource intensive scenery (such as Orbx Ireland) with a resource intensive aircraft can sometimes reduce your FPS although personally I don't get hung up monitoring FPS providing FSX looks smooth. However for the purposes of this post I just did a flight using the default Baron from Eiresim Shannon across to Coonagh using Orbx Ireland, George Keogh's great Irish airfield freeware and Daniel Florentin's wonderful Irish scenery addons and the average FPS is in the mid 50s on my system. The combination of high demand scenery and aircraft can also sometimes push FSX close to it's VAS (Virtual Address Space) limit of 4GB causing an Out of Memory error warning followed by a CTD although. Using the default Baron on this flight I still had over 2GB of free VAS remaining but switching to a higher demand aircraft for the return flight saw the amount free VAS drop to 1.2GB and the frame rate to 40 but still smooth.

A steam guide. I'll link it later if you need it.

Yes please. I think I know which guide you're talking about, but it will be useful for everyone else.
