Rainbow Six Siege is currently on sale on Steam and I'm considering buying it, but I'm not sure it would work on my laptop. I have the Acer Aspire 3 A315-53g-52cq with a Geforce Mx 130 as graphics card and an Intel Core i5-7200u as processor.
Rainbow even ran on the worst settings on my laptop, and it was super bad.
So it might not be that good, but it should work if hslt is on the lowest settings
Yes, the game will be on. At 1080p with the lowest settings you can expect around 50 fps. Because this is a shooter, I would recommend going down to 900p to get a little over 60Fps. The game won't look particularly beautiful, but it won't run disastrously if you are willing to compromise on resolution and settings.
