CS2 pros say 360 Hz is where the refresh-rate race stops paying - and the frame math agrees

Every monitor launch this year has been a bigger number on the box. 480. 500. 600 Hz. And every time, the same question lands in my DMs: do I need this to stop losing duels? Now two people who actually get paid to win those duels have weighed in, and the answer is the one I've been giving for a while.

PC Gamer put the question to two Counter-Strike 2 players from Luminosity, Azuwu and yxngstxr, at a Logitech G event in Warsaw. The short version: the jump to 360 Hz is real and you feel it once you're there, but above that the gains get smaller and more personal, and both pointed out the obvious problem that almost no PC can actually produce 600 frames per second in a real match. The site had already argued 360 Hz is the sweet spot for competitive FPS; the pros didn't disagree.

I'm not surprised, because the math has been shouting this for years. Frame time at 240 Hz is about 4.2 ms. At 360 Hz it's 2.8 ms. At 480 Hz it's 2.1 ms, and at 600 Hz it's 1.7 ms. So 240 to 360 buys you roughly 1.4 ms per frame. 360 to 600 buys you 1.1 ms - and only if your rig delivers a locked 600 fps, which in CS2 with its current engine means a top-end CPU, tuned memory and a map that behaves. Drop to 400 fps on a 600 Hz panel and you're paying for headroom you can't use.

Where the milliseconds actually hide

Here's what a 600 Hz box can't fix. Your mouse click has to survive a USB polling window, the game's input sampling, the render queue, the GPU, and finally the panel's pixel response before it becomes a visible shot on screen. On a well-tuned system that whole chain is somewhere in the low double digits of milliseconds. Shaving one more millisecond off the display interval is a single-digit percentage of that chain. Meanwhile a bad config - vsync sneaking on, a full render queue, a background app eating a core - can add multiples of it.

That's why I keep telling people to fix the boring stuff first. Cap your frames so the pacing is flat instead of spiky. Turn off every overlay. Check that your panel is actually running at its advertised refresh in Windows, because you'd be amazed how many 360 Hz monitors are sitting at 144 out of the box. Then log your 1% lows, because a 360 Hz panel fed by a game bouncing between 250 and 500 fps looks worse than a 240 Hz panel fed a locked 240.

There is one honest argument for the very high refresh panels: motion clarity. Even if your fps can't match the rate, a faster panel with good overdrive smears less during flicks. But that's a pixel-response story, not a refresh-rate story, and the players PC Gamer talked to were clear that whatever you get past 360 is marginal and depends on the individual.

My take, having tuned a lot of setups for people convinced the monitor was their problem: if you're on 144 or 165, a 240 or 360 Hz panel is the single most noticeable upgrade you can make. If you're already on 360 and still losing the trade, the display is not the bottleneck. You are. Or your config. And I mean that kindly, because mine was too.
