DnDBeyond is SLOWING down my PC since approximately Feb. 23, 2026. As a former software tester for many years, I ran several tests with my computer to determine why my PC is slowing down in the past several days, and the smoking gun (the culprit) is the DnDBeyond website. Two other DnDBeyond players also reported similar slowness with their PC and laptop and smartphone (using the DnDBeyond app.). The computer slowness gets worse (slower) when I open multiple DnDBeyond webpages or tabs. As soon as I close all the DnDBeyond webpages and tabs, then my PC runs as fast as normal.
Yet as soon as I use DNDBeyond for several minutes and open two or more DnDBeyond webpages/tabs, then my PC slows down too much.
What hardware are you running this on? Is there anything else running in the background/browser that could have affected this? What program did you use to try & diagnose this?
Because my out-of-date(hardware-wise), 16-tab(including video)-running, and well-worn laptop isn't slowing down, and because of that, I want to try & help diagnose your issue.

I use D&D Beyond across firefox and chrome, over mac, windows, android, and iPad, both website and app, and I've not noticed any slowdown. It's strange that you mention your friends report slowdown with both the app and the website, because with the exception of the native browser within the app for the character builder, they're completely different environments.
Are you running any extensions like AboveVTT or Beyond20? Or anything else that might be modifying DDB like ad blockers? Things point more to this being a localized issue rather than one endemic to DDB itself.
Not OP, but I'm encountering similar issues since the dice roller update. GPU usage has skyrocketed, getting as high as 220% on Firefox. Primarily, this appears to occur where dice rolls could occur (i.e., character maker and character sheets), and then increases when dice rolls do occur. I am running uBlock Origin, but this is consistent with it turned off and on. No additional extensions. Hardware acceleration is turned on.
Thanks, MaedraDawnkeeper, for reaching out to me to offer to help diagnose my PC slowdown. Today I opened 4 DnDBeyond character webpages with 4 of my PCs+NPCs, and did a few dice rolls and my PC slowed down noticeably. ---> My PC config is as follows: Hardware: AMD Ryzen 5 5600x, 32GB RAM, Nvidia GeForce GTX 960 GPU with 2 GB, MSI MAG B550 Tomahawk Gaming Motherboard. Software: Windows 11 24H2 and Bitdefender app (it uses < 1% CPU and ~ 4% RAM) and Malwarebytes paid app (uses << 1% CPU and ~ 1% RAM per Task Manager). Browser: Chrome latest version. No extensions running. Internet speed is 361 Mbps download and 42 Mbps upload, latency 11 ms, jitter 1 ms per Fusionconnect. Similar internet speed results testing with Speakeasy and Ookla Speedtest.
---> Prior to opening any browser window and with no apps open except Windows Task Manager, my PC is running at ~ 2% CPU and 20% memory utilization, 0% disk, and 0% network. Opening Chrome browser with only a simple homepage loaded raises CPU temporarily (seconds) and then back to 2%, and 21% memory (instead of 20%). When I initially open the DnDBeyond /account page there are no major changes in CPU usage (~ 2%) or RAM usage ( ~ 20%). No other webpages are open except DnDBeyond.com webpages in my tests.
---> Use case: When I DM, I typically need to have 5 or more characters (mostly NPCs) open in my browser. I don't notice a slowdown with webpages loading or a slowdown with my ---> mouse cursor until I open 4 (or more) character webpages at DnDBeyond.
---> Comparisons: If I open 5 YouTube webpages in the Chrome browser and play all 5 videos in parallel, there is no noticeable slowdown with my PC or mouse cursor.
As another test, I opened 20 webpages in the same Chrome browser and didn't notice a PC slowdown or mouse slowdown if ("if") NONE of the opened webpages are DnDBeyond.com.
If I click on dice rollers in DnDBeyond for any of my characters when i have 4 or more characters open, then my PC gets even SLOWER for several seconds or perpetually slower (making the mouse cursor lag too much to use my mouse) until I close that browser session and restart my browser. My mouse driver is the latest driver per Microsoft Windows 11.

No PC or mouse cursor slowdowns experienced with any other websites, even if I have dozens of websites open. The slowdowns with my PC only occur (as of a few days ago) with 4 or more characters open in DnDBeyond. My PC didn't have mouse slowdowns in January 2026 or in December 2025.
I cannot duplicate this. I currently have 12 DDB pages open including 6 character sheets and am able to roll dice and open apps with no issue on a Windows 11 PC. I just checked the iOS app on my iPhone 13 and there are no issues there either.

OK. From the looks of your setup, your computer is newer than mine in some ways, but has some older parts, too.
Hardware-wise, you've got a better NVIDIA than I do.
So we can eliminate that as the problem.
I replicated the conditions you set(4 characters open+16 tabs), opened Maps, and saw what happened.
From what Task Manager told me, there were odd spikes during dice rolls, but it quickly went down after those.
Did you run your test while rolling digital dice vs not rolling said dice?

(My PC has much better stats, but I haven't used it in 3 months due to travel.)
Prior to opening any browser window and with Discord voice chat open and Windows Task Manager, my PC is running at ~ 14% CPU and 64% memory utilization, 0% disk, and 0% network.
Opening Chrome browser with DNDBeyond character, it runs at ~ 20-40% CPU and 76% memory utilization, 1% disk, and 0% network.
Adding a VVT tab to play session or rolling dice, it runs at ~ 44-60% CPU and 82% memory utilization, 1% disk, and 0% network.
When rolling dice, about half the time, I am unable to see my own dice rolls (set to roll to everyone) but others can see. A few times, rolling also causes my entire screen to go black, requiring alt+tab to bring it back. Fellow party members report intermittent issues with being able to view dice rolls as well.
Use case: When I play, I typically need a minimum of Discord, 1 DNDBeyond character sheet, and 1 DNDBeyond VVT tab. When I DM, I typically need Discord, 4 or more DNDBeyond characters, DNDBeyond VVT, 2 or more DNDBeyond resources open in my browser. Prior to this week, I had only noticed a slowdown if my internet was having issues, regardless if I played on laptop or desktop. This week, I noticed a significant slowdown and the issues noted above.
Weirdly, I've managed to solve it on my end by changing what dice I'm using. Not sure whether it was the change or if the dice itself was the issue, but switching from the Airships of Eberron dice to the Forge of the Artificer dice resolved the CPU/GPU problems. Can't promise it'll be a universal solve, but it might be worth giving a go.

iPhone and iPad having major difficulty even looking at characters let alone getting in maps or rolling dice. I posted separately as well.

I have also just within the past few days had performance issues (slowing down) on my pc as well!
