Hmmm, even after uninstalling everything the same problem persists O.o this cannot be right, And i havent even applyed patch 2.0.2 so there should be no reason ____________________________________ EDIT:Could it be that EM4 Stores game files elsewhere on my computer other then the root directory? Just shooting ideas though. EDIT: My specs are as follows if anyone requires them: - 2 x 8600 GTS (PCI-e) Three Displays in use. - 4 GB DDR 3 Ram - Gigabyte P55-USB 3 Motherboard - 2 x 1 TB HDD - Intel Core i5 2.67GHz Also for those experiencing the 'Lag' With the green circle around units this IS actually a hardware issue as after updating my computer to the above, I am able to select almost 35 units at once without experiencing lag.
