input delay in specific games

[Bradie]

Recently I played Valorant and Rainbow Six Siege, and I got keyboard input delay when I turned off my vsync. After I turned on the vsync, there is no more input delay. But my monitor is 60Hz only, I want higher frame rate.
I tried check games file either reinstall the game, but nothing changed. Currently the only possible way for me is turn on vsync.
CSGO is totally fine btw.

Spec :
Intel® Core™ i5-6600K
EVGA GeForce RTX 2070
32GB RAM 2800Mhz

Keyboard : HyperX Alloy FPS

Use nvidia control panel option "fast sync" if getting fps over the refresh rate matters so much. It will allow vsync like behavior without capping frame rate.

By the way, how are you measuring "keyboard input delay?" I doubt this is in the range of human perception.

What you are experiencing is input delay as a result of your CPU. When you enable V-Sync, it caps the framerate at your monitor's refresh rate and thus your CPU is no longer running at 100% ensuring that new input from the player is processed immediately.

You may not be able to see it on a 60 Hz monitor but V-Sync itself does also introduce input lag, quite a bit in fact. The solution to your issue is to use the in game frame limiter. For Rainbow Six, that's in the settings. CSGO is a bit more complicated as you'll have to dig into the files. You want to limit your FPS to the point where the primary thread / threads that the game is using sit around 95% usage.

You may want to consider a CPU upgrade as the bottleneck FPS wise is going to lean heavily on your CPU. The 6600K tends to top out at 90 - 100 FPS in that game. Ironically you can get around 186 FPS in the built-in benchmark, which is terrible for determining actual performance.

I would not advise fast sync.

1) It only helps in GPU bound scenarios
2) It introduces noticeable stuttering

The key to the lowest latency possible for gaming is to keep both the GPU and CPU below 95% utilization.

Thank you both for your reply
I may consider a upgrade. Currently, is AMD or Intel CPU better?

Depends on your budget and use case scenario. Best budget gaming CPU is the 10400F. Best mid range gaming CPU is the 5600X. The 5600X also doubles as an excellent all arounder as well. Best gaming CPU period is the 5950X but you are talking only 1-2% over the 5600X for more than double the price.

If you need gaming and multi-thread performance, you may want to consider a Ryzen 3700X / 3900X/ 3950X. You can find something like a 10700F for around $290 USD but even though it's 8 core multi-threaded performance wise it's only as good as a 5600X. It's also slower in games, single thread, requires a quality VRM, and will output more heat.

You should also consider that AMD also has PCIe 4.0 motherboards if that's an interest to you or not. For gaming though, it shouldn't be a factor unless you plan on keeping it for more than 3 years.

Very well written. kudos.
