I ran into 2 wierd things today shortly after logging into TT
FYI there ware around 650 people on..
at first all was normal..
ISSUE #1:
Out of nowhere, the game started being really jerky, like I had low FPS, but I was at 60. It would only do this when i looked in the direction of alot of trees.
I have
NEVER had this problem before, no settings changed.. no nothing. my system can run the absolute dog snot out of this game under virtually any circumstance.. let alone when im more or less alone over a forest.
setting the vis distance down helped.. as soon as the trees went away, the jerkiness did as well, untill i got lower and the trees came in again.. then it got jerky again.
this progressively got worse the longer I flew, until I was forced to log and come back in, at which I could play for a short while and it would start up again.
ISSUE #2:
I started getting this strange blackout..
when I just just BARELY get enough Gs to cause a SLIGHT blackout effect.. I would get this:

If I pulled harder and get deeper into blackout I would get this..

I have NEVER had the game do this, dont know what caused it..
I left the TT arena, opened the same map in Offline mode... neither problem occured, game ran smooth as glass and the blackout was normal..
exited offline mode.. back to TT.. same issues again..
Rebooted system.
same issues.

in game: game is using ~900MB ram out of 4gb
says is using 110 of 256mb video mem:huh
says is using 0 for textures

frame rate stays pegged at 60 except under very demanding circumstances (20+ planes, all hangars smoking etc etc) then may drop as low as 50.
Im stumped, Ive made NO changes, im using the same settings I always use.
