Corsair M65 RGB Ultra Review (Page 3 of 4)

Page 3 - Subjective Performance Tests

This is where the fun begins. After installing Corsair iCUE, I adjusted the M65 RGB Ultra to my personal settings. This included modifying the sensitivity and calibrating the mouse for my current mousepad. Afterward, the tracking performance test began. This was done by using it for my typical applications. This included simple web browsing, gaming, and Microsoft Office. Some graphics testing was also done in Adobe Photoshop. As the Corsair M65 RGB Ultra is designed for both first-person shooter or FPS and multiplayer online battle arena games or MOBA, I used games such as Valorant and League of Legends to test this mouse. Please note these are subjective tests, but we will attempt to make them as objective as possible with my cross-reference testing methods.

As previously mentioned, when it comes to mouse grips, I personally prefer to use a palm grip, but I can also adjust to claw grip if needed. I found that the Corsair M65 RGB Ultra is a mouse practically made for claw grip users due to the placement of the sniper button. The finger grip style also works very nicely with the small size of the mouse, and the crisp clicks of the Omron switches only further complements these grip styles. While the mouse fits decently into the palm of my hand, it started to get uncomfortable after a longer period due to the small size of the shell. Therefore, I would say palm grip users may want to opt for a larger mouse. Even at its minimum weight of 97g, this is still heavy for a wired mouse in 2022, and not super advantageous for first-person shooter games requiring swift actions for aiming and shooting. With that said, I found I was still able to have solid performance with this mouse when playing FPS games.

When it comes to sensitivity, I prefer it in the 3000 to 4000 DPI range, even when gaming, including FPS games. The 100 DPI to 26,000 DPI range of the Corsair M65 RGB Ultra will have users enjoying the flexibility of sensitivity options. The fact that the Corsair M65 RGB Ultra has a maximum sensitivity of 26,000 DPI using a PixArt-based sensor at a price point below the Corsair Scimitar RGB Elite is impressive, even if very few users would choose to go up to a sensitivity that high.

The Corsair M65 RGB Ultra is advertised as a gaming mouse, so I ran my tests on FPS and MOBA games. When playing Valorant, I was impressed with how responsive the Corsair M65 RGB Ultra was. I like to hotkey common commands such as reloading and melee to available buttons on my gaming mice. While reloading and switching to melee, I found every button was quite responsive. The Corsair M65 RGB Ultra gave quick response rates when in combat, further complemented by the crisp clicks of the buttons. When playing MOBA games, the tracking movement was very standard, although the heavier weight of this mouse made large movements more difficult, especially when compared to lighter mice like the Corsair Katar PRO XT and DeepCool MC310. I found this to be especially true with League of Legends, where I was constantly swinging the mouse around to move my champion to different areas of the map.

While the Corsair M65 RGB Ultra is best utilized for games, I found that it continued to give good performance when using it for more work-related applications. When using Microsoft Office to write reports and track project progress, this mouse continued to deliver on its tracking performance, especially when going between multiple cells and sheets in Microsoft Excel. When doing my regular browsing between different websites, the side switches gave a very nice response, with going back and forth between pages being almost seamless. A big part of this is thanks to the Corsair Marksman sensor. This sensor gave pinpoint accurate responses and incredible control with a maximum tracking speed of 650 IPS.

I found the Corsair M65 RGB Ultra to be very responsive and precise with the switch clicks and maximum polling rate of 8000 Hz. This is not a polling rate that you will find in most mice today and is unique to Corsair. The response time was very consistent with no input lag when testing from 100 DPI to 26,000 DPI. There was some noticeable observable jittering at 26,000 DPI, although this is not entirely surprising given how high this sensitivity is, which I feel very few people would use. At lower sensitivity levels, I experienced no jitter issues. The lift-off distance was also very low. From testing using my mouse pad, wooden desk, and kitchen tablecloth, I found there were no issues with tracking.
