Hi,
Others and myself have mentioned this before but the performance problems you see really only have one solution. A newer version of vam that actually uses more than 1 cpu core AND actually takes advantage of the GPU/FPU for math processing. The engine the current version of vam uses does not take advantage of multiple cpu's or the gpu both because of how meshed coded it but more the limitations of the game engine he used. This 'SHOULD' be resolved in release 2.0 when that drops maybe this year but more likely early next. There are tiny tweaks you can do to give you MAYBE 1 or 2 frames boost but nothing to improve it to the level you see other vr stuff running at.
The good thing is Meshed is aware of these issues and is serious about getting rid of them.
Some stuff to give you a slight improvement:
-Install VAM on a solid state drive. NVme would be the best.
-Set the user display settings to middle of the road vs Ultra (yea it kills alot of the better creators works but it does allow you to view them.)
-Make sure if you use an oculus (yuk facebook) headset that the facebook software isn't handling the display or set to auto. Just shut it off in the display settings. Also i strongly recommend you set your computer firewall to BLOCK any and all Facebook/oculus traffic in and out. We did a seperate review of this on reddit years ago about all the data facebook gets from your pc whenever you boot up and logon. You don't even have to have oculus running!
-Try and get rid of duplicate custom files. Far to many creators had reused textures and other creators stuff and it just makes a huge mess in VAM. Having 20 copies of the same hair is just asking for a lag fest.
This will all help improve the performance some. Your not going to get blazing performance even if you shell out tons of cash for a killer rig. I know i have one and performance going from my i5 to an i9 with a 3090 was minimal and really not worth it if all you do is play vam. (I game professionally so i had an excuse to go blow a wad of cash vs just blowing my wad!)
