For more information about this issue and possible fixes, visit
our support site.
If you call a support person, give them this info:
Stop code: IRQL_NOT_LESS_OR_EQUAL
stop code: KMODE_EXCEPTION_NOT_HANDLED. no other game does this. im starting to think its the anti-cheat driver, but idk how to prove it. my rank is sinking fast.
ive already updated the GPU driver, reinstalled teh game and run a quick memory check... nothing obvious turned up. the crash still hits in teh middle of matches... my rank and my sanity would both apperciate any help.
