osu! version: 20161020cuttingedge

I can't interpret the log very well but there might be easy fixes to this
Try enabling "reduce dropped frames" in settings to see if this helps
Make sure an antivirus program isn't interfering with osu!
If you're in windowed mode, try enabling full screen or letterboxing

"Reduce dropped frames" - nothing happened, still game is randomly dropping frames
I don't have antivirus on pc ( I know it's weird but true)
I'm only playing on full screen mode with 1920x1080 resolution
Drops started appearing after Windows 7 installation, on 10 it was working correctly but I was forced to change OS
https://osu.ppy.sh/ss/6408679 <---- Screen about 1 sec after lag

This might be a stupid question, but does osu! Have enough RAM to run smoothly?
Check task manager too see if you have enough

Task manager didn't noticed any "jump" in usage, all other programs is closed when I'm trying to play ;v
On the graph in osu when game is getting lag spike "Swap buffer" is the only line bigger than others

See if changing frame limiter helps in reducing dropped frames,
Is your current resolution native to your monitor?

Nothing changed with frame limiter
Yes, native

Try running in compatibility mode and see if you notice any changes in performance
Does the spike happen in beatmaps with videos, or storyboards? Try playing another beatmap if this is the case, or disable the SB/video
Try disabling shaders if it's enabled

Does the problem persist in osu! Latest version?

Compatibility mode make game little like laggy and game still lag spikes but little less ammount of them
Osu! Cutting Edge - Latest version, I tried other versions but same like on cutting edge
Shaders and everything what can lag game is disabled

Make sure your drivers are updated and at the latest version
Enabling/Disabling enhancements in your driver settings might help

Drivers installed yesterday, it's up to date
Everything in control panel is set to performance not image quality

Is osu! Set to run with Integrated graphics? Try changing it to run with your GPU, or the other way around

Integrated graphics is disabled in Device Manager, only main GPU is active

Could you provide a screenshot of your task manger while in processes tab?
Make sure "show all processes" is checked

The bottommost process has a CPU usage of 98%, if I am seeing this correctly,
Most common causes of this are viruses, try scanning your PC for any malware or virus

Also, see if the Handle of this process is high (right click the columns, add coulmns and select "Handles")

It's process what say's how much % of cpu is free to use, explaining i had 2% cpu used at taking screenshot moment ;p

Have you recently installed osu in a new drive? This might seem like a last resort, but try fixing osu
Hold shift and open osu! And try to make changes
By chance, if osu! Is installed in a flash drive, install it on your local drive

Nope, I installed osu like always after format

This might be a long shot, try enabling Windows Aero just too see if this would affect the performance.
Does the spike happen more often? Does it happen more on SB load heavy beatmaps or with videos?
Does the spike happen whenever you play only or does it also happen in the menu, or anywhere else?
