Requirements

Windows 10 or 11 (64-bit). Run as administrator. The GPU pack is built for NVIDIA cards; the other three packs work on any system.

Before you apply

Create a Windows restore point first. The tweaks change system settings, and a restore point is the fastest way back if you want to undo everything.

Optimizer questions

What actually changes on my PC?

Each pack writes a set of registry, service, driver and boot settings aimed at lower input latency and steadier frame times. The Home tab shows a score so you can see how much has been applied.

I have an AMD GPU. Is it still worth it?

The GPU pack targets NVIDIA drivers, so on an AMD card you will get the CPU, Network and Windows packs. Those are where most of the latency gains come from.

Do I need to restart?

Yes. Several tweaks only take effect after a restart. Apply the packs you want, then reboot once.

How does the licence work?

You get a key by email. Paste it into the app on first launch and it activates on that PC. New PC or fresh install? Open a ticket on Discord and we will reset the key.
