When Windows 8 was released, I updated all my computers to Windows 8 and later now on Windows 8.1. I have an ACER Iconia W500 X86 tablet with AMD APU that run on Windows 7 32bit and now on Windows 8.1. This tablet is 3 years old now! While I have to say that the support for Windows 8.1 is not officially granted by ACER aynmore, the hardware still works pretty well with the original AMD drivers. Although there are problems with the drivers after revision 12.10. The ACER software overlay for Bluetooth, WLAN, Energy Options and the like does not work with newer drivers and due to their missing support probably never will. With the latest AMD drivers the whole display does not work, so you basically have to live with outdated drivers. Anyway, this is not a problem with modern, still supported hardware I suppose.
Back to the topic of the thread though.
All games that run under Windows in general also run on Windows 8.1 on the tablet. Depending on how demanding they are the hardware itself is limited of course. For example, I run games like World of Goo, Plants Vs. Zombies and tried various adventures (e.g. Beneath a Steel Sky, Broken Sword) without performance issues. There is a problem when you need a keyboard (for entering a name for example) because all full-screen applications do not recognise when you switch into a text-box and fail to bring up the virtual keyboard. Even if you manage to bring up the virtual keyboard, you will have a problem because the screen size and resolution is pretty limited, so you won't see much of the screen while typing. Those games require to have an USB keyboard (and a mouse can sometimes also not hurt) to be plugged into the tablet.
However games that were designed to run on tablets as well, like the games from the Windows app-store, have all run very well and without problems on the tablet so far. The most demanding I tried so far was probably PinballFX 2 which is great fun on the tablet.
I have yet to try very hardware intensive games, like Civilization 5, but the harddisk space of the tablet is limited anyway (only 32 GB with 14 GB left after Windows is installed and a SD-Card slot for another 32 GB) to put on modern games that take more than 4 GB space anyway. Maybe I will try BattleWorlds Kronos in the next time. :-/
Long story short, yes games from GOG will run on Windows 8.1 tablets like they do on a comparable desktop PC, but only within the same hardware performance limits and some may need additional input devices.
If I would nowadays chose a tablet as a mobile gaming device, I would probably try to get a convertible with build in keyboard because you won't have to carry around another keyboard in case you urgently need it.
