window dragging is really laggy

Question

this is an issue I've had for a while, but that i no longer tolerate.

for a while now, dragging around any window in windows 10 takes a while to respond, starts moving slowly and it only gets exponentially worse if i start "shaking" my mouse, like if every direction i moved my mouse with, the window moved in that direction for a second before moving in another. it feels awful, and I've tried everything i thought might've caused it.

I've built my computer almost exclusively for playing, so i have parts/peripherals of decent quality.

below is what happens when i quickly move my mouse around and release click. two cursors appear, but i cant do anything untill the window stops moving. im trying to follow the cursor on the window to show that there isnt any lag with the "free" cursor

Hi Alex. I'm Greg, an installation specialist and 9 year Windows MVP here to help you.

Can you remember when this started? Do you have a System Restore point going back to before that date: http://home.bt.com/tech-gadgets/computing/how-t... ?

1. Update the Display driver from the PC or Display adapter maker's Support Downloads web page for your exact model number, HP Serial Number or Dell Service Tag - from the sticker on the PC.

While there check also for newer chipset, BIOS, network, sound, USB3 and other drivers, comparing to the ones presently installed in Device Manager reached by right clicking the Start Menu.

if this doesn't give you the latest or ideal driver for what you need, compare it to the driver offered by the Intel driver update Utility here: http://www.intel.com/content/www/us/en/support/...

or the Nvidia Update utility here: http://www.nvidia.com/Download/Scan.aspx?lang=e...

or the AMD autodect utility here: http://support.amd.com/us/gpudownload/windows/P...

For Display issues one fix that is working is to Roll back or Uninstall the Driver on the Display Device > Driver tab, restart PC to reinstall driver.

You can also try older drivers in Device Manager > Display device > Driver tab > Update Driver > Browse > Let Me Pick.

Then you will know you've tried everything in addition to Windows Update drivers.

2. Adjust and try different Screen Resolutions at Settings > System > Display until it looks best and acts right.
3. If necessary go over this checklist to make sure the install is set up correctly, optimized for best performance, and any needed repairs get done: http://answers.microsoft.com/en-us/windows/wiki...

Start with Step 4 to turn off Startup freeloaders which can conflict and cause issues, then Step 7 to check for infection the most thorough way, then step 10 to check for damaged System Files, and also Step 16 to test a new Local Admin account. Then continue with the other steps to go over your install most thoroughly.

4. If nothing else helps you can run a Repair Install by installing the Media Creation Tool and choosing from it to Upgrade Now. This reinstalls Windows in about an hour while saving your files, apps and most settings, solves many problems while also bringing it up to the latest version 1809 which you need anyway and by the most stable method. http://windows.microsoft.com/en-us/windows-10/m...

I hope this helps. Feel free to ask back any questions and keep me posted. If you'll wait to rate whether my post helped you, I will keep working with you until it's resolved.

Hi Alexandros

The symptoms you are presenting with are all an indication that your video card device driver is the cause . . .

Try looking for a slightly older version of your video card device driver to see if your system stabilizes . .
