The Real Secret of Smoothness

[zENNy]

I’ll get straight to the point without dragging this out, guys.
First of all, I’m using a Ryzen 7 7800X3D CPU and an RTX 4060 GPU. A short while ago, I did something a bit crazy: I unplugged the DisplayPort cable from my RTX 4060 and connected it directly to my motherboard, meaning I switched to the iGPU of the 7800X3D.

After installing the AMD Radeon software and testing CS2, the result was absolutely shocking. Even though I was only getting around 130–140 FPS, the game genuinely felt like I was getting the full 240Hz experience. With a few minor tweaks and by lowering the resolution to 640x, I managed to reach around 200 FPS, and the smoothness is unreal.

This honestly makes no sense. On the RTX 4060, even at 700 FPS, the game felt like 75Hz.

This means one thing: there is definitely either a software-side bug/problem on NVIDIA’s side, or an issue related to PCIe/power/cabling.

Please try this yourself and share your results with me.

Of course it's not software, if it would be then millions and millions of people would have those problems, not just a few of us.

PCIe connectors are apparently the most sensitive to electric noise and interference out of all components. I still think that dirty electricity enters the PC through monitor (monitors have the shittiest possible power supplies, without any filters), and not through PC PSU. And then, if you connect the monitor to the GPU port, the noise goes straight to the GPU - and your PSU cannot filter that anymore, it can filter only the electricity that enters through PC power cord.

I've noticed the exact same thing on my setup (7800x3d + Nvidia 4080). Smoothness on iGPU is unmatched compared to GPU.

I also tried using the motherboard DP port with MSI Hybrid Graphics (using the GPU through the mobo DP), and while fps is good, it still causes the same issue. The smoothness just isn't there whenever GPU is involved.

I also tried different PSUs, and even tried to power the GPU with a dedicated PSU. No difference.
Any ideas on different things to test regarding this would be appreciated.

Hi. You need to play on an IGPU for a few days and it will be exactly the same as on a 4060 (bad)

[cuaderno]

Well have you tried using the 4060 but capping the fps to a value that you can maintain constantly stable, like 200? Or Using VRR while capped within monitor range?

Going uncapped to reach 700 fps idle at spawn and dropping to a third to it the second an enemy appears will make the game unsmooth, maybe that is the lesson

[zENNy]

A small update. A few days have passed and, unbelievably, the smoothness is broken again. It feels like every time I restart the computer, either the voltage settings get messed up or the shader files get corrupted—I can’t really tell. The stuttering and latency have started again.

Usual temporary effect, you can get similar affects by switching to a usb port you haven’t used in a while/different controller, then eventually it’ll end up in the same position.

if you use fiber optic displayport the emi doesnt transmit through it because its light vs steel. Easy to prove with google.

yet another silly thread like this we all know at this point we get temporary effect of smoothness but the issue always returns its like a plague but without remedy unfortunately

It is probably temporary because the capacitor gets filled, stores energy, but after a while, it can no longer do so. Otherwise, the issue could be EMI/RFI or grounding.
