Testing
I have been gaming with this mouse for a good three weeks now; everything from Counter-Strike 1.6, Source, Half-Life 2: Episode 1, Call of Duty 2, Supreme Commander, and Oblivion. I have used the smooth and rough side of my Func pad and a standard office type cloth mouse pad.

The earlier G5 has issues with skipping. Some attributed it to the first generation of laser mice, while for others it depended on the surface it was used with. Logitech has since released a firmware update for the old mouse that should remedy skipping issues on most mouse pads. I don’t have many gaming pads let alone all of them so I can’t test them all and report back to you. However, I did try making this mouse skip on COD2, and both versions of CS. I know most people who tend to find these “skipping” issues on the old G5 were low sensitivity players. Not being a low sense player, (3 sensitivity in CS, 800 dpi), I wanted to be sure to test a broad spectrum of settings in various games, on various pads trying to replicate the skipping. I tried .5/1/3/8 sensitivities, 400/800/2000 dpi, low and medium Windows mouse speeds and most all of the combinations on both sides of the Func and the standard mouse pad. I could not once get it to skip, or flake out. I also tested in Photoshop at a low speed, high and low dpi drawing lines as fast as possible and not once could I see any skips. Now whether or not this mouse uses a newer firmware than the updated one for the last G5 I am not sure, nor can I assure you that it will not skip on other surfaces, but it certainly passed with flying colors on this setup.

I realize in our latest G5 Battlefield 2142 review Thomas noticed how he couldn’t for the life of him get the mouse to skip either. But then he commented that after weeks had gone by he noticed some performance issues. I have yet to experience anything like this. Whether or not that was a different laser engine compared to this new revision I don’t know. We can try to get some answers from Logitech however.

As far as in-game this mouse is a joy to use. Snap movements, responsive repositioning, and accurate shooting are the standard with this mouse. In the three weeks I have used this not once did I come across a moment where the mouse caused me an issue in game, dying, missing a frag, etc. The mouse has performed admirably in all the games I have used it on. It sits right up there with the 518 and MSIE 3.0 (new version), which were my last two mice, as tops in performance. The mouse not only performs great in FPS games but I tore it up in Supreme Commander. Accurate multi-unit selections even at the distant levels of the map view, quick selections without having to reselect them were all the norm when playing this game.
