HELP cannot play devilian

wow thanks nice advice first time for me doing all of this myself im learning as im doing it.
yes i have RAID after checking my hardware but honestly i dont have a clue what it does or if i need it.

When i install my OS i went to the dell website after downloading pc driver support( did not use it) and manually downloaded all the drivers listed that my PC needed. I just hope i needed all of them cause that is what i did.

Just a note when it comes to troubleshooting anything with PC stuff my mind is equivalent to a 5 year old.

Ok good news patching all of my OS updates has fixed that issue and now i am able to load isboxer with all 3 accounts. i am having another issue though.

Now i have all 3 clients loaded but my mouse cursor is not broadcasting to all of them. even when i move my mouse to one of them and try to click anything it is like my mouse does not work except for my main cursor moves around. i have all the clients in windowed mode and i tried full screen as well no change.

also my windows are very hard to see due to everything being scaled so small.
