PC not Accepting Reinforcements

Basically, it's got nothing to do with the hardware (although the pop-up implies so.)
Just go to your preference. txt file of your MIITW folder, set:

"UNLIMITED_MEN_ON_BATTLEFIELD:FALSE" to
"UNLIMITED_MEN_ON_BATTLEFIELD:TRUE"

That would make them all appear, but you are still limited to your 20 unit army, unless you let the AI control them.
I've had some "fun" 1500 men VS 6000 timurids with this setting.

Excellent! Thanks for the answer.
