In brief: Enough Alder Lake owners have recently reported web browser performance issues for Intel to spot the issue and provide some solutions. The source of the problem is a specific model of integrated graphics card, and the company’s suggestions are mostly standard troubleshooting.
This week, Intel allowed that recent drivers for its UHD graphics 770 iGPU can cause severe stuttering in Chrome and Edge browsers. Reported issues include very slow scrolling and click responses delayed by approximately two seconds.
The problem affects 18 12th Gen Intel CPUs including multiple 12500, 12600, 12700 and 12900 models. Go to Settings > System > About to check your CPU model. To confirm your GPU model, go to Settings > System > Display > Advanced Display Settings and look under Display Information.
Intel first suggests making sure Windows and your browsers have the latest updates, which you should do for almost any troubleshooting. Then try a clean install of Intel graphics drivers. Intel and this website offer generic Intel iGPU drivers, while your motherboard manufacturer’s website probably has custom drivers.
If that doesn’t work, Intel also says to disable hardware acceleration in the browser that’s having problems. In Chrome, it’s under Settings > System, while Edge users will find it under Settings > System & Performance. If your system or browser is installed on an HDD, switching to an SSD may also help, but that would be a drastic and potentially costly step.
