My PC has requirements to run Gears of war 4 in Medium or high and I'm doing badly

You could try turning off vsync, and ambiant occlusion. Also, you may want to see if you can find a INI tweak guide.

Hi,

Forgive me, I've had to manually put those through Google translate from Galician to English. I take it 'Alta' means high and 'Media' is medium?

What happens when you put everything to Medium?

While your specs are ok for this game, the Core i3 7100 isn't a high end CPU, and, while a Geforce 1050ti is much better than any integrated GPU, it's not high end either. However, it should be capable of 60FPS with some tweaks.

Are you running 'Fullscreen' and not 'Fullscreen' windowed?

If so, it is high and medium when I put everything in the middle it goes up to 25 but they are not constant and I execute it in full screen

¿Está ejecutando algún programa en segundo plano?
Pruébalo sin ningún navegador de internet, y cosas como Discord. El primer paso es minimizar todo lo que puedas.
Si funciona mejor, entonces sabemos que uno de los programas es el problema, no lo hace, entonces otra cosa es el problema.

I already did it is more optimize everything I could windows and even so the fps do not go up

GPU up to date? Your PC specs are fine. It can run almost any game at med/high depending

I would suggest you try to tweak the 3D settings in Nvdia Control panel and also try the Geforce experience app that will help you modify settings for your game.
