Much appreciated!  Hope to be back soon.

I think single-board computers, e.g. Raspberry Pi, are UEFI / Secure Boot free, though they are a bit low on spec for gaming ...

Do Raspberry Pi clusters make it any better for gaming ?

That's a good point ...
What I have seen with Raspberry Pi3 clusters, if I remember well, is that the RAM is additive, but the max CPU power is not.
So with a 64 x Pi3 cluster,  as shown in  https://www.youtube.com/watch?v=Jq5nrHz9I94
- max CPU power is still only 1.2 GHz
- total RAM will be 64 x 1GB = 64GB
- graphics quality greatly improved

I may be wrong here, but I think for high-end gaming, peak CPU power needs to be much much higher than 1.2Ghz.  Though the 64 x Pi3 cluster has great parallel processing capacity, I think it would be too slow for any demanding gaming - what do the rest of you think..?

This it is a bit different
https://www.gchq.gov.uk/news-article/gch...-computing
It was shown at a local fair here https://www.thebigbangfair.co.uk/
(also they involved the National Engineering Competition for Girls )

From reading it sounds like it can be possible to increase processing power, but not the processor on each board ?
Some how to behave a little like the multicore processor and multi threads, eg; how the each processor perform a task , or part of it/thread.
It would need to be coded the games for it like this principle -  https://en.wikipedia.org/wiki/Porting
for that to work.
Commercial games maybe it won't give the coders who can do that the source code.
There may be Open Source games who would.
I don't know if there are any coders who do work on this, or if they already have done it even in the past, as I don't know about gaming.

I did a bit of searching on the internet and found that though you can build a supercomputer with a large Pi cluster,  and have great parallel-processing capability, it will be no good for high-end gaming. 

By the way the Pi has neither a  BIOS nor UEFI, appearing to function in quite a different manner at boot-up, the design of this being closed- rather than open-source ...

Thank You for info about Pi boot from GPU with closed firmware  

Have you looked at the link I posted previously how they flash the firmware of CPU on laptops to remove UEFI to make it unclosed, can it be done to make high end gaming computers without UEFI, like you are seeking, or not ?

I'll take a closer look...
