Disclaimer

Just from the get go this is an issue that seems to affect G-Sync monitors. I am not able to test with freesync but I’ve had this problem affecting me for years and never known it was to do with this till I actually got off my ass and figured it out. If this this widely known! Sorry! Hopefully I’ve helped someone!

Backstory

I have a G-Sync monitor. Whenever something drops to low FPS whether it’s a level loading or the game just gets choppy, performance in other applications are hampered even if they shouldn’t be. World of Warcraft is one of those. It’s always running and when I tab out I have it drop down to 30FPS. This causes applications weirdly on my second monitor to match this frame rate. To test this issue I dropped it down to 8FPS and it got even worse. The biggest issue of all, is that whenever I hearthstone the game loads and drops down to 1FPS causing everything to become unusable on the second display.

The Fix!

Now the simple fix would be to just turn off G-Sync. That’ll stop whatever this issue is. We’re going to look into why this is happening, but a quick workaround is just to open something graphically intensive on your other monitor. In my case, I wanted to record the problem happening, but opening OBS fixes it. Interested to learning why this is happening and if anyone out there has any deeper insight into why, would love for you to share in the comments below. I’ll update the post as we learn more.

Things Tried

I did my research! I tried thing such as editing Nvidia Inspector settings for multi monitor optimizations along with a barrage of Nvidia Control Panel settings of GPU Scaling etc. Nothing seemed to work except turning off G-Sync or having another application open in this case OBS to stop it happening.

Quick fix on this error. To be clear I tried the following solutions:

Safe Mode with Networking
Creating a players2 folder in the install directory
Launching just the exe
Reinstalling the game
Reinstalling Battle.net

None of these worked. However this solution worked for me. First download the zip file below

players2 Download

Extract this to your Call of Duty Modern Warfare 2 Remastered install directory, for me this is here. C:\Program Files (x86)\Call of Duty Modern Warfare 2 Campaign Remastered
You should now have a players2 folder in that directory along with a Data folder and a main folder
Go inside the Players2 folder and rename the folder in there to your Blizzard Account ID. You can find this by going here: https://account.blizzard.com
Open Dev Tools (Right click Inspect Element)
Go to Application
Inside the application window go to Local Storage
Click the https://account.blizzard.com
And follow the screenshot to find your account ID.

Once you have your account ID, rename the folder called 125568351 to whatever your blizzard accountID is. You should see it in the bottom left of my screenshot. This is inside the players2 folder and your game should now launch. If the game asks do you want to launch in safe mode? Click no. If the game asks if you want it to auto detect video settings, also press no. Sometimes if you press yes it’ll still fail to launch!

There seems to be an issue with Call of Duty Modern Warfare 2 Remastered creating this folder. Hence why it complains about disk space as I presume that’s just the default error it gives when it cannot create a folder or a file.
