Extreme lag in any DirectX game that I play after upgrading to windows 10! (GT 840M)

[paragonx9]

Hello everyone! I recently upgraded my computer from windows 8.1 to windows 10. As soon as I upgraded my computer, however, I have been facing extreme lag during pretty much every DirectX game that I play. I'm talking 4 FPS lag. Before the update every game ran perfectly fine, with no issues whatsoever. It was the windows 10 update that ruined it for me.

Here's a list of things that I have tried:

- Restarting computer
- Reinstalling windows 10 (without keeping windows settings, etc.)
- Removing drivers
- Updating drivers through geforce experience
- Installing Beta Drivers (only Windows 10 beta driver was a driver that was released a pretty long time ago)
- Installing old drivers from windows 7/8
- Going into the Nvidia control panel and messing about there. I made sure that the graphics card selected was mine and not the onboard one.

I also noticed something strange. I tried out the PPSSPP psp emulator and to my surprise, it didn't lag at all! So I went into the settings and noticed the renderer was set to OpenGL. So out of curiosity I switched it over to D3D9 and then the lag rained down on me. I then opened another OpenGL game and it worked fine as well, so the issue seems to be limited solely to DirectX for some reason. Everything else in my PC works fine.

I've been stuck with this issue ever since windows 10 came out like a week ago. It's killing me... Any help / feedback would be appreciated, thanks!

None of those methods is acceptable for upgrading drivers. There are two things I'd recommend doing. First I'd try the DDU method outlined here:

If that does not solve the issue, I'd back up my important data and do a clean install of 10. Many users with issues after "upgrading" have found them to be resolved with a clean install of the OS followed by installing the latest drivers from the Nvidia website.

Hi, thanks for the reply! When I said I uninstalled the drivers I meant with DDU, sorry for being unclear about that. I tried again just in case and that didn't work.

As for a clean install, I also tried that. I did the one where it uninstalls everything and creates the windows.old folder with my old stuff, or does that not count? Should it be a 100% clean installation?

Thanks again!

Yeah, that's an upgrade, not a clean install. You need to choose the option that doesn't include leaving any files, folders or settings. I think it's the last option at the bottom. Use the tutorial I linked to above as a guide. Delete ALL the existing partitions on the drive during the installation (Except for the recovery partition from the OEM if you wish to be able to install your older OS later if you do not have physical media for that OS.) then install to the unallocated space.

If you DO have an OEM recovery partition, it would be preferable to save that to a secondary location like an external drive and then delete that partition as well from the target drive you are installing the OS on, but is not strictly "necessary", just preferable. Or creating installation media from that OS would have worked as well, for use later, but it's probably too late to worry about that now.

Alright, I'll try that then Thanks!
