fps drops / 20% cpu ussage moving mouse in some games

I am using logictec g15 key board / g700s mouse and software recently in 2 games red orchestra 2 / rising storm I get 768 fps in main menu and move the mouse even a inch or two she's drops down to 345 fps in game I'm around 97 fps ultra 4k and she drops 25 fps same as fallout 4 now I have 125 polling rate have tried closing the software no avail and with fo4 if I go to game properties and compabilty select run as administrator and dpi ceck it's ok but ro2 you can run as administrator steam says a error. Now if I run game booster before opening the games all is fine and game booster doesn't close gaming software weird. ..

 

Do you have another mouse you can use to test it with? I have a G19 keyboard and a G500 mouse, and I've never had any of these problems.

I remember I had a problem once where if I plugged in my mouse, I could hear this weird buzzing/whining sound. Just plugging it in would cause it, and it would get worse if I started moving it around.

Turned out that it was the motherboard which had defecting VRMs..

 

I have a Daedulus Apex G303, no issue since I swapped motherboards though.

 

it's either mobo/chipset driver related, or logitech drivers.

 

Game booster, mouse drivers..and this is just what you know/telling us, your pc's DPC latency is probably going sky high,you don't need any of that crap.

I'd uninstall everything and go from there. Windows reinstall if possible.

 

Nevermind...

 

Check with LatencyMon ,, using 1000 hz usb polling causes CPU Usage jumps even on top Cpu.

 

Not trying to be a smart ass, but do you have any sources to back that up? Because quite honestly I've never heard of that before.

 

Yeah I don't think I have heard oc'ing cpu/ram/gpu can cause lag but I could be wrong ? I'm not here to be right .
I have my cpu oced to 5.0 ram 2133 stock gpu's were @ 1200 core each vs 1090 stock I ran stock settings same issue , ok restart pc with out logictec game panel lcd ( g15 key baord) or game panel starting up ..same thing up to 15% cpu on desk top with mouse , red oreschstra rising storm is the werst to notice it , ok I reinstalled nvidia drivers in safe mode with ddu came back In ok tested games same thing . Found out in my bios I have my integrated igpu ( integrated graphics in cpu ) was on ! Even though I don't have intel.drivers instaled so I shut it off in bios and re instaled nvidia 362.00 and now life's good again fps in red orchestra 2 rising storm is normal again ( 72 to 140 fps 4k ) vs 30 to 50 before.
My fix was a few weeks back I reset cmos with out keeping intergraded cpu graphics off and when installing nvidia drivers it does some weird stuff even though it wasn't showing up in device manager ! Thanks guys :banana
