S***

before I start fix your problem can you give me your laptop/PC specifications so I can compare it to my system

then we see what we're dealing maybe the problem is headwear because I upgraded my system and the problem for DMC SE 4 is solved however if you have dealing with low frame but strong system here try this but first backup exe file:
Low End Settings For DMC 4 SE (I think you can adjust your settings there like orginal so no problem).
