Is Unity RAM Dependent?

[PiberiusWilde]

Hi there, I've recently just got into gaming again and most the games that I played uses the unity engine i.e. Escape From Tarkov, My Summer Car, etc. and I've noticed that with the most recent update of these games, mainly EFT. The game has been running slower on my laptop (i5-8265u, 8GB, MX250). I used to get around 60-65 fps but I capped it to 45 fps so it doesn't burned my finger, but now I'm struggling to get 15fps. I last played these games about probably about the end of last year. Now I've heard that unity games uses a lot of ram because unlike other engine which basically what we see is what got rendered, unity just render the whole thing, so it put the whole game on ram and there's no such thing as *despawning*. Is it true that unity is very RAM dependent?
