I get around 60+ FPS when running Warframe at medium settings which is pretty well optimized but still pretty hardware intensive.
For games like Titanfall 2, I think I stay around 60ish FPS when running on all low settings although I do have the FPS capped at around 70. The relatively low resolution may make everything look pretty bad but its playable at least. I guess for games like Overwatch, that doesn't really matter.
These games really heat up my laptop so definitely get a cooling pad. Here's the one I use:
