Recently I reinstalled win7 ultimate 64-bit, an upgrade from vista. Once I installed everything (ie drivers and whatnot) I seem to get a general frame dip+ping spike at random intervals, lasting about 10-20 secs. I’ve tried turning off the MMCS and disabling audio driver, but it seems the issue is not with sound and/or the MMCS and network throttling. It’s no problem with mumble as well, since it occurs with or without mumble on.

Drivers are all up to date, and before saying my laptop cant run/get a better pc, TF2 ran fine with 120fps on Chris’ Highframes and generally 30-70 ping to local UK servers when I was on windows Vista.

Does anyone have a clue?

Yeah, disabling the MMCS and lowering/disabling network throttling via registry edits (found on SPUF) is what I tried, no luck.

Ping spikes and fps drops are as follows: normal, about ~30-60 ping, 100-120 fps. Spike, about 100-300 (normal) or 200-450 (rarely, but does happen), fps 100-120 (normal) or 20-70 (alongside that rare ping spike).

I’ve tried whitelisting Steam folder (standard procedure I do with every reinstall), Wlan optimizer doesnt work (i do have significantly higher internet surfing speeds though), laptop temperature is normal (ie proper ventilation and all, rarely ever overheats), used game booster in vista before but never noticed any performance difference with or without it. I hardly ever run anything in the background, usually its just steam + any other game. Drivers are, I feel, quite irrelevant because I only experience this problem with games on steam, my StarCraft 2 is still in perfect order.
