On the subject of mouse latencies, I keep hearing, seeing or reading that there is no difference between wired and wireless mice. Let’s leave the topic of Bluetooth out of this for now! Various channels on YouTube and other media outlets like to show off manufacturers’ latest mice, claiming that wireless devices with dongles (paired with high-speed tech) can rival wired mice on an e-sports level. Well, these days a strong claim is usually enough to influence buyer behavior. However, hardly anyone has measured this to validate their claims. That’s exactly what we want to catch up on today!
That’s why we’re taking a close look at it all today. It’s a good thing that NVIDIA and LDAT exist, because in version 2 you can actually measure something like that! You can see exactly how that works and what comes out of it in the end in my review today. First I will briefly introduce you to NVIDA LDAT V2 and my measurement setup, and then I will say a few words about it before backing up my measurements with an ANOVA and an MSA. Keyword: Measuring system capability!
First of all a few more links to already published articles by me and Igor. This is also where the new readers among us can get up to speed!
What exactly is NVIDIA LDAT? Here the article from Igor: Link
Is NVIDIA LDAT a capable measurement system for system latencies? You can find an article about it here: Click
Does the use of the USB port matter? You can find the answers here! Link
So, now that everyone knows that LDAT has measurement capability in the area of system latency and the USB port (whether 3.2 or 2.0 or connected to the CPU or chipset) doesn’t matter, we can take a look at my test system.
| CPU | Ryzen 7 5800X (PBO 2 CO negative) |
| Mainboard | MSI MAG X570 ACE |
| RAM | 4×8 GB Crucial Ballistix RGB 3600 MHz CL16-17-16-36 (OC) |
| SSD 1 | Toshiba Transcend 110S 256 GB (System) |
| SSD 2 | Crucial P2 1000 GB (Games) |
| SSD 3 | Crucial P2 1000 GB (Games) |
| SSD 4 | Samsung 512 GB 840 Pro (Backup) |
| CPU Cooler | Aphpacool Icebaear Aurora 360 |
| Power supply unit | Seasonic Prime Platinum 1300 Watt |
| GPUs |
MSI GeForce RTX 3080 Ti Suprim X – water cooled ice block GPX Aurora (GeForce Driver 496.13) |
| Sound | SoundblasterX AE-5 Plus |
| Keyboard | Cooler Master SK 622 (Red Button) via USB @1000 Hz Polling Rate |
| Mouse | ASUS ROG Chakram Core @1000 Hz Polling Rate (NVIDIA Reflex Latency Analyzer Support) |
| Monitor 1 | ASUS ROG Swift PG279QM @240 Hz [1440p] via DP (Nvidia G-SYNC with Reflex Latency Analyzer) |
| Monitor 2 |
LG 27GL850-B @144 Hz [1440p] via DP (AMD FreeSync Premium, G-SYNC Compatible) |
So a few small changes I made to the test system. The AMD Ryzen 7 5800X now runs with PBO 2 and the Curved Optimizer (info can be found here: click). Furthermore I overclocked my ram from 3200 CL16 to 3600 CL16 and the graphics card now has the abbreviation Ti and not FE anymore. That should be sufficient at this point. We’ll go one page further and now look at the measurement setup for measuring mouse latencies.
