why should your monitor the reason of false computing?
How about your graphicCard?
Maybe to hot? Anything?
I've a high end machine, with super cooling, but TM2 on all high screws my temps. over all specs i've on all other games.
Only to show...
TM2 all on high
CPU 67° (I7-2600k)
GPU 71° (still a old gtx260 OC)
BC2 all on high
CPU 53°
GPU ~60°
As you can see, my hardware needs more power than on Bad Company2 wich is a Hardware based game.
If your Hardware is too hot it will "loose packets" like on TS3 with high ping.
And that is normal...so i really think it isnt you monitor at all...more anything other part of your machine.
TM2 is still beta...sure it has a new engine, but who said that all is perfect till now? Even the Engine isnt at it's end and maybe not right balanced till now.
