Hi guys, I know it’s a discussion that exists a lot here, but so far I can’t solve my problem.
It turns out that I’ve been having problems with FPS “Limited by MainThred” for a long time, however, I even changed my processor to Rayzen 9 and my video card is 3080, and even so, I still don’t go beyond 36fps simulating on “High” 
- AMD Ryzen 9 5900X, 3.7GHz
- Gigabyte B550M AORUS Elite, Chipset B550, AMD AM4, mATX, DDR4
- Memória DDR4 Geil Orion, 16GB 3000MHz, Red (x2)
- SSD Hikvision E-100 256GB , SATA III
- Galax NVIDIA GeForce RTX 3080 SG
Does anyone know how I can improve isos? it’s an expensive computer hahaha, it should be better, or not?
Sorry, I’m really bad at these things and thanks !
