[2023] What's your average Memory usage. VRAM & RAM?

I don't have immediate metrics, but both of those seem rather high for Vanilla unless you have an extremely large base with a lot of complex shapes.

You have to make sure you're looking at the right values also.
Commit is potential but is not actually being used.
Working Set or Private will tell you the amount of RAM actually in use by the application.

You also need to make sure that you are looking at the specified program data in Resource Monitor, and not just looking at total system RAM usage.

I mean, just sitting here idle writing this post, by system is using 17.3 of 32GB RAM. I have about 20 tabs open, Steam is downloading stuff, Discord is up and I'm in voice. File Explorer, Epic, and other background tasks are running.

However if I open the game, getting to the menu shows Commit 2.9GB, and Working Set at 1.3GB. VRAM did not increase significantly from the 1400MB that it sits at when I'm not playing anything.
Loading into the map (Navegane), I see VRAM go up to 4741MB. System Commit is 8.6GB, and working set is 5.3GB.
Playing around a bit, I see 5,493MB VRAM, Commit of 9.8GB, and Working 5.5GB. Total system is 22.7GB
Hopped into the Gyro and few from Diersville to the Desert city, and landed on top of the Higashi tower. VRAM 5784MB, Commit 10,5GB, and Working Set 6.1GB. Total system is at 23.1GB.

Now I'll try it on one of our servers with a 10k map. I did not fully exit the game, so main menu now shows 5017MB VRAM, 9.7GB Commit, and 6.1GB working set.
Logging into the server I see VRAM at 5899MB, Commit is at 13.6GB, and working set is 9.1GB. Total System is now 25.9GB.
After playing for a while, VRAM is 5829, Commit is 13.7GB, and Working set is 9.26GB

Also, I will note that my FPS on average was 140-144FPS until I got to the skyscraper where it was 45-60FPS. Running around a good sized town not near a skyscraper is 90-120FPS.

For reference, because this does make a huge difference, here are my settings. I'm playing at 1440p resolution.
