I installed Ubuntu on my Macbook Pro recently. But DOTA 2 is very much laggy in Ubuntu 16.04. It runs crispy in OSX. I tried updating machine and all, but no use.

The graphics card shows Intel Haswell Mobile in Ubuntu and Intel Iris Pro 1536 MB in OSX. Is it a graphics related problem? How can this be fixed.

Note: I have seen Dota 2 running fine on Ubuntu with laptops of very ordinary specs.

Some more information as per comments:

  1. The output of lspci | grep VGA is

    00:02.0 VGA compatible controller: Intel Corporation Crystal Well Integrated Graphics Controller (rev 08)

  2. It plays 60 fps 4k videos perfectly fine.

  • Also, can you play a 1080p 60FPS video (such as youtube.com/watch?v=aqz-KE-bpKQ) off of YouTube fine? Make sure to select the 60fps mode in the youtube menu.

  • I have updated with the required information. I also tried to install AMD Graphics driver, which did not help. So uninstalled it back.

I had this problem, and I managed to solve it on Arch linux. The problem was that OpenCL drivers were not installed. I guess the basic steps are same, so here they are:

  1. Run $ neofetch command to check what Graphics card you are using. //Mine was Intel Crystal well.
  2. Go to intel site and find what is the microarchitectre of your chip. For e.g. mine was Haswell as seen on https://en.wikichip.org/wiki/intel/crystal_well. My processor is also listed i7-4770HQ.
  3. Install the relevant driver, as from this page - https://wiki.archlinux.org/index.php/GPGPU. Mine was intel-opencl. Restart your computer.
  4. Run $ clinfo . You should see a platform registered. OpenCL is enabled now.
