The issue

You’re tab into Call of Duty: Modern Warfare 2, Warzone (or any other COD for that matter), and the music you’re enjoying, the video you’re focusing on, or just media in general stops, buffers, and pauses. This is caused by a lack of performance in your browser. Your game is eating every system resource to squeeze the most FPS, which is usually a good thing.

We can solve this with a few simple steps.

Limit FPS in-game (Best fix)

Yes, having more FPS is a good thing. But letting the game run wild on your hardware isn’t a better solution.

Yes, you can drag the “Max FPS” slider to 300, but odds are you’re not going to reach that with current-gen or next-gen hardware unless you’re playing on the absolute lowest settings in a tiny window.

All you need to do is start playing a video or whatever media is buffering in the background and tab back into the game. Start by matching your monitor’s FPS rate in-game. If you have a 60 FPS screen, you likely already have a smooth video at this point. If you set it to 165, 144, or another high refresh rate, you’re likely not even reaching that. The game is still pulling far too much.

As much as it hurts, this is the most effective and sometimes the only option for fixing YouTube videos that won’t play when you’re playing Call of Duty: Modern Warfare 2, Warzone, or any other COD game.

Lower video quality

If you’re watching YouTube at 4K on a second monitor, it’s likely asking for resources your computer does not have, while COD eats everything available. Start by lowering the video quality - It’s off to your side anyways. Focus on the game, and watch a 360p, 240p, or even lower video in your peripheral vision.

You can always tab out and raise the quality if you need to read or focus later. This isn’t ideal compared to limiting the game’s usage.

#Use local media or not videos

If you’re watching YouTube and it buffers, another option is just not using YouTube. If you listen to music on YouTube, you should consider downloading music or, more likely, using a streaming service like Spotify to get your fix. If you’re not already a subscriber, this is a hard push for people who listen to music for free on YouTube, but most platforms offer ad-supported or free tiers.

Again, limiting the game is your best option here.
