I crash every time we jump to lightspeed to escape the enemy ship in the first Flashpoints. It's maddening. I have a Radeon card, HD 7770 2 gigs and Windows 7 64-bit.
My roommate and I are having the same issue. We just re-subbed a few days ago since leaving shortly after the 1.2 patch. Never had this problem before during beta through 1.2. If it truly has been a known issue since 1.4, that makes me pretty sad.
