After launcher issues, game lags so bad its not playable

i just received a lengthy reply by GM Chaos explaining that the Exit code: -1073741819 error, also known as c0000005 , is a known issue and points towards a manufacturers problem (backed with a series of error messages they found from the logs . I am just not buying it that things worked smoothly as silk for 2 weeks and then all of sudden : boom ( at the date where the new launcher is rolled out for good)
