Fixed the input lag issue.

[naporitan]

I finally solved the desync and input lag issue.
To do this, I had to take certain steps:
1. Set Secure Boot to "Custom" mode and load the default keys.
If "Standard" mode is currently active, your system is not functioning correctly; you need to reinstall Windows and select "Custom" mode with default keys before proceeding with the installation. To avoid hidden issues, you should reset the CMOS and restore BIOS settings to default before installing Windows.
2. XMP/EXPO disabled; JEDEC must be used.
3. You need to fully update Windows and update all applications via the Microsoft Store, as some of them are important system components.
4. Install the drivers from the motherboard manufacturer's official website, then update the chipset and GPU drivers.
You do not need to manually remove previous versions of the chipset and GPU drivers; the chipset or GPU installer itself will correctly remove the old driver version.
5. Enable GPU scaling in the driver control panel and leave the 3D settings at default.
6. Do not disable DyAc/GSync technology or its equivalents.
7. Plug the mouse into a USB port connected directly to the processor, and the keyboard into a chipset-controlled port; ensure nothing else is connected to the keyboard's line.
Do not use Motion Sync technologies, etc.
8. Enable NVIDIA Reflex and AMD Anti-Lag 2 in the game.
9. Do not use ultra-mega low-latency tweaks.
Do not change the power plan, timers, priorities, etc.
Give up tweaks entirely.
10. Use `fps_max 400` for 144–360Hz monitors, and set it to 600 for 500–600Hz monitors.

I'm not lying; there's no point.
I'll explain a few points.
1. Why did I decide to use Jedec instead of XMP/EXPO?
Answer: I had a gaming laptop that didn't have abnormal input lag, desynchronization, etc., and I noticed that the RAM was running on the Jedec profile.
And I've recently looked at the top-end gaming laptops, and they all use Jedec profiles!

2. Why do I need to switch Secure Boot to Custom mode?
Answer: I checked the official guide from the motherboard manufacturers, and they say you need to enable Custom mode!
For the record, I have a Gigabyte motherboard, and Standard mode is set by default. I don't know why they did it that way, but that mode is for different purposes!

I could go on and on, but you can find all the information yourself. The point is that all the information is taken from official sources! And the system should work correctly!

Here comes that greenhorn again, cluttering up the forum. I’m not even going to read this nonsense. When are they going to ban you? Maybe we’ll start insulting you as soon as you post something? And automatically lock your posts? I think that’s a good idea—not everything written on forums is true. It’s 2026; this problem has been going on for 11 years. Some people get lucky, others don’t! Guys smarter than you have scoured the entire internet and double-checked everything possible—yet you just keep spewing nonsense.

he might be right... doing some testing in the order he explained, seeing some good results. would have to reset windows to completely test, dont know if i will

[cursedgamer12]

wait hes right. im sorry for saying i hope you get cancer and aids. literally set custom secure boot with default keys(everything else in bios default), set windows to default settings and nvidia, then clear cmos. best performance ive ever seen in 3+ years!

[Brutek_Vladimir]

What if i just turned off secure boot completely ?

then the problem comes back: input lag, display lag, everything is shit

Here we go again....just one question for you and try to answer....

People who don't know anything about computers simply buy a PC, leave everything at the default settings, keep Secure Boot in Standard Mode, install CS2, and just play. They don't have any desync, input lag, etc...HOW???????? just ban this guy please.
