Depende yan sa unit mo. If you're using a PC and i3 and GeForce GTX 650/PCIe/SSE2 below ang specs mo hindi kakayanin. Yung canary and nightly build kasi sa Pokemon Sun is need at least i5-8300H CPU and GeForce GTX 1050/PCIe/SSE2 ang specs or the better available.
If mobile naman, early access palang yan so don't expect too much kahit high specs pa phone mo.
