just a note...there are several versions of graphic lag atm

ATI cards... sorry to say..we suffer alot due to the incompatibility of the drivers, though ATI has post a fix in their latest 14.1a? or something but still there prob persist with most users who are not running windows7 and certain older range of cards.

Mac users > though bliz has claim they made a fix in patch 1.0.2, yes its playable now...sort of..try window mode and reduce every graphics settings you can think off and off anti aliasing. for older mac like mine ..MBP 2009 sorry la..you can only AH.

NVIDIA certain older gen cards will have lag issues, no news on why and when fix will come since this is less common compared to ATI cards.

theres been many many post on bliz forums on so called fix. using 3rd party software like msi afterburner to lock the FPS, to me it still lags. u can google it and try it.

patch 1.0.3 brought back whatever they fix in 1.0.2 so its pathetic again..but still playable. just eye sore cos there seem to be delay in the graphics


as for why SD card works better then the ssd...reason is theres a bug with the buffer/caching file, thats why you move it to a SD card for a faster reading, but if not wrong if you card is a cheapo low class slow reading card, same issue? cannot confirm this as i only read it on some forum somewhere.
