"Use Browser Hardware Acceleration" Setting In BNet Client

Some random person on the forums mentioned this odd fix that I think is important for the devs to look at. Unchecking the “use browser hardware acceleration” setting in the bnet client removed most of my in-game lag in D4. The big thing it removed was the lag I used to get from changing shards. I think this deserves a lot of attention.

Portaling back to town used to be lag city.

All day my latency has been going back and forth from 100 to 700 no matter where in game I was including multiple disconnects. How could they miss this! Someone needs to beaten with feedback!

My D4 latency used to be on average twice what my WoW latency usually is. Now it’s more normal.

I’m currently hovering around 84 msec but its stable.

Same. About 70 to 80 ms. The alternative to this atm is to shut down the bnet client while playing.

Been spreading the word in-game and everyone is amazed its working lol. Blizzard needs to release an official response to help us peons out.

It won’t get rid of all lag, just the really predictable lag.

It’s stable lag. Count our blessings.

Its far simpler to just have the Bnet app exit when launching a game.

Turning off the hardware acceleration can make the launcher run a bit weird. Just FYI.

And this has been suggested now for over 3 weeks and has varying degrees of success.

Not to mention, having the app exit also frees up resources. So win win.

How I fixed my constant frame swings:
Disable Hardware Acceleration in Battle.net application
Disable Hardware Acceleration in Discord
Disable Hardware Acceleration in MS Edge
Enable DLSS

I’m dubbing this a placebo effect at this point. I turned it back on and the game didn’t get more laggy. One thing I know for sure that will stabilize your game is playing at lower FPS, like 75.

where exactly can you turn this on/off? Is it an in-game option or within the Battle.net desktop app or?

if you want to see if it will even help, just exit the launcher after starting the game.

But the setting is under settings in the launcher (the gear cog top left after you click the battlenet logo)

You can also just set the app to exit on game launch instead. Turning off the feature can affect the performance of the App. Closing the app actually frees up resources anyway.

ty for this, giving the exit launcher option a try first

What graphics card are you running to require this? I’ve tested the game on both an RTX 4090 and Intel Arc A380 personally.

It’s not a “requirement”, it just makes the game run 100x smoother.
