my computer lags randomly, particular under high virtual loads.

[zackerydr]

imagine pretty much it lags extremely badly, in any high performance related activity, roughly either every 10-7-15 ish seconds. i tried everything. and i mean everything so far. from removing my batteries. removing Microsoft power management drivers in the batteries drivers in device manager. i used register editor, i have factory reseted my computer. i have tried to look into my bios, but its locked, and i cant do much their except making my fan always on (also my bios limits my VRAM of my gpu to 512 megabytes, it doesnt bother me that much, as my shared VRAM carries the rest in gaming, or other rendering settings, in the exception of certian unoptimized games i assume, or applications that explicitly target vram, its not much of a issue, but a relating problem)(i have zero overheating problems, screenshots show that obviously with the gpu heat. i doesnt matter its not exactly cpu temperature, as its simply roughly 12+ Celsius more hot if its to be cared at all. needless to say, it will struggle to overheat, so its not that, but any suggestions on maybe it is heat anyway, hit me up and stuff.). i have even somehow been able to access legacy utilities for a more advanced, and powerful version of a "registery/registeriderd pro" of some varient or something like that, and it didnt work either. i changed everything i could find online. any more help, or exactly a pure solution to this would be great!  my computer is a 15-fc0047wm, uses a ryzen 7 7730U with integrated AMD Radeon RX Vega 8 (Ryzen 4000/5000) graphics processor.

Hi @zackerydr 

Welcome to the HP Support Community! We're here to help you get back up and running.

Thanks for laying this out with such clarity—and I’m genuinely sorry you’re still stuck with this. You’ve clearly gone above and beyond in trying to resolve the lag, and the fact that it persists every 7–15 seconds under load despite clean resets, registry tweaks, and thermal stability tells me we’re likely dealing with a firmware-level bottleneck or power delivery constraint that’s not exposed through standard diagnostics.

Let’s walk through a more targeted recovery strategy that builds on your efforts and focuses on VRAM allocation, power throttling, and driver-level latency.

 

Root Cause Possibilities

Based on your HP 15-fc0047wm with Ryzen 7 7730U and Vega 8 graphics, here’s what could be happening:

 

1. VRAM Bottlenecking

• BIOS locks VRAM to 512MB, and while shared memory helps, apps that explicitly target VRAM (e.g., Roblox explosions, rendering engines) may stall waiting for memory paging.
• Windows dynamically allocates shared memory, but if system RAM is under pressure, it can cause stuttering.

 

2. Power Delivery Throttling

• The 7730U is a low-power chip (15W TDP) and may throttle under sustained load, especially if the system is trying to balance CPU and GPU usage.
• HP’s firmware may enforce aggressive power-saving policies that override Windows settings.

 

3. Latency Spikes from Background Services

• Windows 11’s telemetry, Defender scans, and HP background services can cause periodic spikes.
• These often manifest as micro-stutters every few seconds, especially during high GPU load.

 

Targeted Recovery Steps

1. Force High Performance Mode

• Open Command Prompt (Admin) and run:
  powercfg -duplicatescheme e9a42b02-d5df-448d-aa00-03f14749eb61
• Then go to Settings > Power & Battery > Additional Power Settings and select Ultimate Performance.

This disables most power-saving throttles.

 

2. Disable HP Background Services

• Open Task Manager > Startup and disable:
  • HP Smart
  • HP Support Assistant
  • Any telemetry or update services
• Then go to Services.msc and set HPAppHelperCap, HPJumpStartBridge, and HP Support Solutions Framework to Disabled.

 

3. Update AMD Chipset and Graphics Drivers

• Visit HP’s official driver page for your model.
• Install the latest:
  • AMD Chipset Driver
  • AMD Radeon Graphics Driver
  • BIOS Update (if available)

Even if Windows says drivers are up to date, HP’s custom firmware may require their specific builds.

 

4. Disable Dynamic Tick and Timer Coalescing

These Windows features can cause periodic stutters.

• Open Command Prompt (Admin) and run:
  bcdedit /set disabledynamictick yes
  bcdedit /set useplatformclock true
  bcdedit /set tscsyncpolicy Enhanced

Restart your system afterward.

 

You’ve already shown the kind of persistence and technical insight that makes this solvable. Let’s push for a fix that respects the effort you’ve put in.
