Hi! Long story short-here are some advices how to increase your fps by couple times(I'm not kidding).
Main thing-I'm highly recommending you to purchase Loseless scaling program on Steam,its very cheap-3 bucks in my region for example. It has an amazing frame generator,that at least doubles your fps in VAM without any flaws.

So here is my small guide for it:
1) After instalation click on app icon(on steam) and open properties,choose beta versions,you need one called beta-beta. The reason why is bcs boomoon said that it works better. But you can try both-current one and beta,wich works better for you.
2) Launch the program and use this settings:
What we need is LSFG 3.0 with x3 mode frame generator. I'm not using scaling in vam,for me it only decreases fps,but you can try for yourself and maybe it will work for you.
With this x3 framegen my fps is getting increased by about 2-2.5 times
3) Improtant(!) You need to lock your ingame fps,I locked my VAM at 60fps for example,more than enought as for me. You can use nvidia control panel for that,radeon usres should have a similar default app. Also game needs to run in a window or fullscreen window mode,but as far as I know VAM is always running at fullscreen window.
4) Actual Launch: so,launch your VAM first,wait until it loads up.Alt+tab and launch Loseless scaling app and press Scale. Go back to VAM window.That's all,in couple seconds your fps should be at least doubled. You can be confused at first bcs fps wil be showed on the top left side,left number-your "real" fps and right number is your actual new fps that you got with framegen.
Also highly recommending to install this plugin from vam hub,it also can increase your vam perfomance by extra 20-30%:
