Game framerate issues

My Celeron 1000m with intel hd 3000 4gb ram runs the game but the frames freeze and stutter. its single channel ddr3 1600mhz (only one dimm slot)

any suggestions? should i buy this Ryzen 5 2500u with vega 8 16gb DDr4 2400mhz laptop? my friend is willing to give it to me for 30 bucks

Your celeron is way below the minimum specs recommended to run the game. Though it will run it (obviously), it will never be a good experience. And each new xpac that comes along will lessen the chance of it even firing up. There’s nothing you can really do to fix it, it’s just too old.

For $30 you can’t go wrong with the laptop your friend is offering you. It should be a pretty night and day difference from your current set up. Still nowhere near being able to max the game out of course, but with settings around the 2-4 range you shouldn’t have any problem maintaining 60 fps. (Valdrakken being the exception. Most people will lag there.)
