Mouse lag

Question asked by junk0680 on Oct 19, 2015

Hello all,

New to this forum, searched for mouse lag questions (in which the fixes dont work, or dont pertain to my situation)...but here goes.


Previous had an nvidia card, which I uninstalled.  Installed Sapphire Dual-X R9 270X.  Since then my mouse has been lagging....not just in games but on the Windows desktop.  Very temporarily fixed by restart.  Within 1-2 minutes mouse lags so bad, the computer is essentially unusable.  The cursor simply doesnt respond to movement for a few seconds then darts across the screen.


I initially had Win 7 Ultimate 64bit, upgraded and subsequently clean installed Win 10 64 bit.

Tried Catalyst 15.7.1 as well as previous.

Currently on Beta 15.201


Turned off vertical sync, dropped max frame rate to 59, tried various anti-aliasing settings. Current resolution at 4k via display port, tried a different mouse etc.


I am pretty sure this is due to the video hardware/software as the problem quickly manifested after the change.  Also, two different OS installs, mice, etc.

Any ideas?


Current specs:

Intel Core 15-2500k 3.3Ghz

Asus p67 Sabertooth


R9 270X with 2GB GDDR5 (core 1070MHz, Memory clock 1400MHz)
