For quite a long time now I've had a problem with mouse stutters mostly while playing CS:GO and other games (the mouse just feels really slow and laggy for a few seconds, happens once in a while). The game itself is not lagging, FPS are stable. After some troubleshooting and excluding the games themselves as the problem originators I have come across the latency checkers and I've found out that there is some latency coming from mostly storport.sys and wdf01000.sys. I'm really stuck with the issue, tried many "fixes" from the internet but nothing really helped. I'm attaching an xperf file (short period of time but I managed to catch the "mouse lag" feel in it) View attachment tests.zipand willing to provide any information needed to solve the issue. Thank you in advance.
It seems a software to crack Microsoft products is present on your machine.
If you shouldn't be aware/conscious of it, I suggest you a full scan with your antivirus and antimalware.
By the way, it is better (faster and more secure) to use an antivirus offline (example: kaspersky rescue cd, that's free).
If instead you should be aware/conscious of it, you should also be aware that in public (and serious) forums it isn't allowed to help (nor trying to help ) someone who activated software with cracks (or similar tools, however they are called).
Will do a full scan to get rid of these, thank you for noticing that. The issue seems to have mostly disappeared after disabling momentum cache on my SSD's software. Storport.sys latency is no longer appearing in LatencyMon. I'm still getting wdf01000.sys latency spikes but they are much less common and less severe - I guess the topic can be closed now.
