I have a Lenovo laptop, Amd A8-6410 with R5 m230 and dedicated HD8500m. My GTA V is running on intergrated GPU (R5 M230) with only 1Gb rather than dedicated GPU with 2GB (Hd 8500m). And the game is running at low performance.
Thanks for the reply, I've also been thinking about playing GTA 5 on my phone but haven't quite found the best one for my phone, ill take gta5mobile.club a try. Thanks
