How to Fix Lagging Dell XPS 15 9570

XPS 15 9570 is Dell’s latest high-performance 4K laptop equipped with a stunning InfinityEdge display. This compact powerhouse features 8th Gen Intel Core processors, up to 32GB of RAM, NVIDIA GeForce video card, and a responsive 15.6-inch touch display.

Despite the computer’s top-of-the-line hardware, several users have reported that Dell XPS 15 9570 is actually prone to lagging. According to reports, the lag happens not just when they’re using performance-heavy applications, but even with simple actions such as opening Windows explorer, watching videos, launching the Start menu, or opening new browser tabs.

The delay spikes when playing games and video editing, with the frame rate dropping down noticeably. Upon checking Task Manager, users discover that CPU, GPU, disk and memory usage are low, which means that the computer’s resources are not maximized at all.

Reasons for Lagging Dell XPS 15 9570

A computer’s slow performance could be associated with varying causes. It might be caused by a faulty hard disk drive, outdated device drivers, corrupt system files, external peripherals, not enough RAM, a bug, or hardware failure. Any of these issues could lead to lagging Dell XPS 15 9570 or other system performance issues.

However, several users speculated that the lag is actually caused by BIOS-related GPU issues. According to several online probes, some Dell XPS 15 9570 computers were power limit throttling their NVIDIA GPUs until the core temperature reaches 48 °C or 118 °F. Most users were only able to reach 60 percent to 70 percent processor utilization, causing task execution delays and slow application performance. Tech companies were also able to replicate the issue, providing credence to earlier claims.

The issue appears to be a GPU-related bug in the recent BIOS 1.4.1 or 1.5 updates for XPS 15 9570. Dell initially denied that there was a BIOS-related GPU bug in XPS 15 9570 laptops, though, saying that they could not find other user reports with the same issue. However, in December 2018, Dell backtracked on its initial statement and confirmed that it was working on a BIOS update to fix the bug.

There is no specific date on when the BIOS update will be released, so users will have to deal with the Dell XPS 15 9570 lag on their own until the fix is released. If you are affected by the XPS 15 9570 Windows 10/11 stuttering issue, you can try some of the solutions recommended below.

Restart your computer for the changes to take effect, then check if the system performance issue has been resolved.

Fix #3: Disable Intel Turbo Boost.

Intel Turbo Boost increases the speed of your CPU by overclocking it. It is useful for doing heavy tasks on your computer, but it also throttles your computer’s performance.

The easiest way to disable Turbo Boost is by using the BIOS switch. Note, however, that this is not available for all computers. Check your laptop’s make and model to determine if it has a BIOS switch, then follow the steps below to switch off Turbo Boost using your BIOS configuration:

1. Click Start > Run.
2. Type in msconfig in the dialog box, then click OK.

6. Choose Disabled, then press Enter.
7. Press F10 to exit the window.

If your device does not have BIOS switch, you can turn off Turbo Boost by by editing your computer’s Power Options. To do this:

1. Go to Control panel > Hardware and Sound > Power Options.
2. Click Change plan settings beside the plan you are using.
3. Click Change advanced power settings.
4. Click Processor power management to expand it.
5. Click Maximum processor state to show the options.
6. Change both On battery and Plugged in to 99%.
7. Hit Apply, then OK.

Fix #4: Uninstall DPTF.

Some users reported that removing Intel Dynamic Platform & Thermal Framework (DPTF) has worked for them. Follow the steps below to uninstall DPTF:

1. Press Windows + R to launch the Run command.
2. Type in apprize.cpl in the dialog box, then hit the OK button.
3. Right-click on Intel Dynamic Platform & Thermal Framework, then choose Uninstall.
4. Follow the on-screen instructions to remove DPTF from your computer.
5. Next, open Device Manager and find Intel Dynamic Platform & Thermal Framework.
6. Right-click each item under Intel Dynamic Platform and Thermal Framework, then click Uninstall.
7. Click Delete the driver software if the option is available. This should prevent DPTF from reinstalling itself when the computer restarts.
