Thank you, everyone.
As for my laptops specs, I am pretty useless at things like this but this is a link to the info on my laptop: http://www.toshiba.co.uk/discontinued-products/satellite-l670d-13f/ if someone with more knowledge in computers can see that it's my laptop being rubbish then do let me know haha.
other than that I have tried it on all the settings avalabel and none have really improved it enough to be played.
