A:AnswerWhile Acer does not test many gaming applications we would recommend you check that the computer meets the system requirements of the application/game to determine if it will work. You can also contact the software vendor to see if they can provide information on compatibility with their software. You might also post your question on the Acer Community where there are many users that post questions and offer help and advice on Acer products. The link is: https://community.acer.com/
