Massive Lag

[Technotorious]

I had massive lag hit about 3-5 mins after playing...it starts gradually then lags so bad it becomes unresponsive. (first t3-5 min are normal and perfect)

Am using 8.1, have tried the following:
- my ISP is fine other MMO work with no lag.
-Tried compatibility mode (all of them)
-Adjusted frame rate and graphics (I have a 2 gig dedicated card)
-checked all files
-reinstalled the patch's listed
-Ran in WINEQ (same lag as stated above)

Any advice would help.
