The steam version of GTA5 runs natively at 7+ FPS on a Linx 10V64 using a Toshiba U3 128GB MicroSD card (it needs just under 69GB of space so won't fit on anything smaller and the Toshiba was the cheapest U3 write speed card I could find). I use a wireless XBox360 controller to play it.
Not exactly an ideal speed but this is GTAV (at lowest settings except for Texture Quality which for some reason works better at high and Reflection quality high because I like it that way) on a tablet. Good enough to drive or fly around enjoying the very nice scenery for fun and but not to play seriously. It can sometimes fall behind drawing the graphic objects when driving full speed, the quickest fix without additional software seems to be to pop into the game menu for a few seconds and it will have caught up when returning to the game.
I was going to install Prolasso to help with that but decided to install the lighter simple version they call CPU Balance instead. Now the game runs ahead of the graphics much less often and is quick and easy to recover, so was well worth doing.

GTAV unfortunately can not run unless your tablet has 64-bit Windows, it has a x64 executable and immediately fails on 32-bit Windows.
I also gave the steam version of GTA San Andreas a try and it ran optimally at the highest settings with anti-aliasing turned off. I consider GTA-SA a good game to compare against, when thinking about whether others would be likely to run full speed.
