What's your GPU? Also, what is your average fps in 6s during mid battles? I have the same CPU @ 4.4GHz and I pretty much never drop below 200fps.

m_limitedcapture_workaround "1" is the default setting though. However, if you hadn't experienced any issues prior it was added I'd say it's safe to disable it.

//net_splitrate 4 // Split 4 packets per frame, reduces choke but is more CPU intensive

Yeah, I've been doing that on windows ever since I discovered that it caused hit reg delays if disabled.

So, I take it that

//net_splitrate 4 // Split 4 packets per frame, reduces choke but is more CPU intensive

is safe to use when you have ample CPU cycles to burn?

Generally, all builds after 1607 messed up a few things including mouse handling. Supposedly m$ fixed it recently but people still report issues so perhaps it hasn't been fixed entirely. Build 1607 will be supported until March 2018(or 2026 for LTSB) so you can hold on updating until then.

Yeah that phrasing was was awful. I feel bad about it now.

Not a fan of dadrock nonetheless RIP. Perhaps AC/DC will finally get a guitarist that won't be wanking around 3 chords for 40 years.

There's something fundamentally wrong with your setup. Your CPU and GPU are excellent and such dips should never occur. I'd start by taking a look into UEFI to check if there isn't some kind of CPU throttling turned on. Also check the frequency of your ram and make sure they run in dual channel. Afterwards, I'd take a look into the GPU drivers. Get nvidiainspector and modify the tf2 profile as follows:

Power management mode - prefer maximum performance
Multi-display/mixed-GPU acceleration - Single display performance mode

I've added -nogammaramp but I haven't used any .icc profiles nor the switch for nearly 2 years so perhaps it was removed in the meantime. It used to work for majority of source based games though. I've tested dota2, csgo, dear esther, black mesa, portal 1+2, tf2, insurgency and so on.

I'm afraid the only way to force an .icc profile would be to use some sort of an injector but that might trigger VAC so be careful.

it makes the game launch slower

Yeah, a good starting point is to measure DPC latency to make sure it's not abnormally high. However, if you haven't noticed any issues such as audio crackling or mouse input misbehaving you probably don't have anything to worry about.

This is purely dependent on your audio stack and hardware. If you get no crackling and similar glitches give it a shot.

They are most likely refubs but apparently MS is going to release a new intellimouse.
