Can you play Rainbow Six Siege on an Acer Aspire 3? Is just down and would like to hollow it out for me
Yes it works if you still have enough memory. But it's not as smooth as a smart gaming PC or gaming laptop.
Yes you can, but not on high settings and a lot of FPS.
Do you know how high I can make the settings and how many fps I would have then?
It is always possible to gamble ^^.
If the graphics are not so important to you, you can tweak the graphics a bit. Laptops like an Acer Aspire 3 don't pack games really well. The game would not run smoothly. The best solution would be to assemble a used PC yourself.
On medium settings you should get 50-60 FPS.
