Question RTX 4090 hiccups 99% 6 fps

[Cheenael]

Hi. My setup is 13600k, MSI z790 Tomahawk DDR 4, 128 Gb ram @2933, RTX 4090. When I play on my 144 hz 2560*1080 monitor, everything is butter smooth. But when I play on my 4k LG CX monitor, I get huge hiccups and freezes in ETS 2 and Satisfactory. Nvidia monitor shows 99% 6-8 FPS every 1-8 seconds in ETS2 and 1562345+ ms latency in Satisfactory every 4-8 seconds. And thoze freezes are really bad. I know my card can run these games in 4k, so resolution is not the case here.

What I have already tried - updating my graphics driver, updating BIOS and CPU microcode, restoring Nvidia control panel settings, turning V-sync on and off, playing with graphics settings.

My TV is connected via certified 2.1 HDMI cable and it had no issues for years. I have been noticing those strange hiccups starting October, maybe. I have all TV HDMI settings on, including VRR. When pressing green button on remote 5-6 times, it shows VRR information as 118.xx Hz (max FPS in control panel set to 119 FPS for active and 30 Fps for background), Gsync on, 3840*2160@120, RGB 10b 4L10 HDR10. When freezes happen in ETS 2, it drops to 40 Hz for a fraction of a second.

I am running Windows 11 23H2 version 22631.4317. Three latest updates are KB5043076, KB5044033, KB5044285.

The only difference between my monitor and TV are resolution, Refresh rate, connection type, G-sync, HDR. Why one is running perfectly fie, and the other has hiccups. Please help. My games or control panel settings are not supersampled.

updating BIOS and CPU microcode
For the sake of relevance, can you please state the BIOS version?

You forgot to mention the make and model of your PSU and it's age.

updating my graphics driver
If you haven't, I'd use DDU to remove all GPU drivers(Intel, AMD and Nvidia) in Safe Mode, then manually install the latest GPU driver sourced from Nvidia's support site in an elevated command, i.e, Right click installer>Run as Administrator.

One other thing is to keep the 4K panel hooked up to your RTX4090 throughout the driver uninstall/reinstall and see if the issue is non alleviated.

BIOS version is 7D91v1F and PSU is 1200 Wt bronze I bought it with 4090 so it's that old, 2 years, maybe.

Never had tried DDU, but I guess it's first time for everything

PSU is 1200 Wt bronze

The what? A Bronze unit with that amount of power must be old or junk. What's the brand and model?

My TV is connected via certified 2.1 HDMI cable and it had no issues for years

Have you tested with another videocable? DP to HDMI2.1 perhaps.

Aerocool KCAS PLUS 1200GM. It's gold. Looks like the previous one was bronze. My TV only supports HDMI cables, no DP

Poor mens Gold unit. Compared to the Bronze unit they added OCP and OTP, which is positive. For the rest it's the same, includes the very low end double forward topology on the primary side.

My TV only supports HDMI cables, no DP

That's why I said DP to HDMI. DP on the GPU to HDMI on the TV.

I don't have that kind of cable right now.

I have used DDU to clean the drivers and install the fresh ones. Also, I installed Nvidia app beta instead of GF experience. Same issues. Also, I set power management to max both in Nvidia and windows. And have disabled DisplayFusion and wallpaper engine - still no joy. I have also installed KB5044380 and KB5045935, because why not. Freezes remain (
