NVIDIA has released a new hotfix driver for its graphics cards, the NVIDIA GeForce Hotfix Driver 551.46. According to the green team, this new hotfix driver will resolve some micro-stutters that players experienced in games when enabling VSync.
Moreover, this hotfix driver will fix a potential stutter issue when scrolling in web browsers on certain system configurations. Additionally, it will improve stability in Immortals of Aveum. And that’s not all. The NVIDIA GeForce Hotfix Driver 551.46 promises to resolve some stutters in Red Dead Redemption 2 on some Advanced Optimus notebooks.
The GeForce Hotfix driver 551.46 is based on the latest public GeForce driver. Therefore, it packs all of its features, tweaks and improvements.
If you’ve experienced these micro-stutters when using VSync, we suggest upgrading your driver. You can do so by downloading this new hotfix from this link. At the end of the article, you can also find its complete changelog.
We’re currently using the 551.23 driver and we haven’t experienced these issues on our main PC system. So, not all PC configurations suffer from them. As such, you can skip this driver if you don’t have those issues. NVIDIA has not listed any performance improvements. So yeah, this driver mainly aims to fix the micro-stutters with VSync.
And… well… that’s it. It will be interesting to see whether NVIDIA will enable TrueHDR for games in its future drivers. Last week, we shared a mod that allowed NVIDIA players to use it in any game. This mod basically allows you to play any non-HDR game in HDR. Think of it as an alternative to AutoHDR.
Stay tuned for more!

I’m surprised! I thought Nvidia drivers were inmaculate and uberperfect..
I dunno why people say this, lol no one claimed they were perfect, just a lot better than the competition. When there is an issue a hotfix comes out pretty quickly, no need to wait for months.
Yeah they are literal perfection compared to the fire hazard coding spaghetti AMD calls drivers
It’s funny you mention fire considering the 12pwr connectors on Nvidia cards.
Nvidia innovates while AMD is 300 years behind. Also, every single instance of 12vhpwr accidents were user error. pretty sad that you AMD cultists are still fixated on this issue. keep using your outdated AMD cable mess while I enjoy my futuristic 12vhpwr connector
they have been doing this for 30 years by now, it’s already way past time to have detailed clarification on which cards received which fixes, and on what OS, what API etc, and oh that’s also a fix for a problem encountered on which drivers?
vsync isn’t good, better off just having realistic settings for your system in games then lock the fps w ncp, less latency as well. That’s funny they mention a game as old as rdr2 and the very niche optimus laptop situation too lol sounds like the fix there is to set windows to use the dgpu for that game and also ncp too. They really need a mux switch for all laptops either bios like mine has or even an option in the settings which then you just restart, no bios finaggling needed by average users. Microstutters seem to be a side effect of the very high fps and refresh rate that the wealthy and hardcore gamers have. Outside of very terrible games of course but I don’t remember the last microstutters in a game of the last couple years, usually it’s very noticeable slideshow or big stutter/hitch once in a while like 77 if I need a restart to clear out ram and such. RDR2 is susceptible to that too but it’s not micro it’s hitches for me.
trevor honey, V-SYNC is crucial if you want to set up your G-SYNC like a pro
Sure if you’re in that small niche, wasn’t speaking to that though, still holds for non-niche players.
I have an old laptop laying around MSI gt72 with gtx 980m 8gb gpu, it has 60hz screen no gsync at all. While i use my desktop for gaming mostly, i use this laptop for all the retro or old games heck it can play most PS4 games in 60fps and some demanding PS4 era games in medium 1080p 60fps. Without Vsync the screen tearing is horrible and frametimes are all over the place. Its a 2015 high end gaming laptop and at that time Gsync and freesync wasn’t very common. If u have non freesync Gsync monitor, Vsync is really important. Games look really bad without Vsync. However in multiplayer games its not necessary to have Vsync turned on.
That’s why I said realistic settings, if you are overdoing it w an old laptop you’re going to get tearing. I never use vsync unless it’s a req like in the older AC open world games like Origins/Odyssey where screen flickers if you don’t have it. Yeah my 2060m isn’t much more than that desktop card, I get no tearing and such just use realistic settings. And as I said to goobertard there I wasn’t speaking to the .05% that have gsync, sheesh you agro notsees.
overdoing exactly what ? Can you elaborate ?
Screentearing doesn’t exist in your world?
There is a better solution than “Vsync: ON”, he mentions it (I think), and that is “Vsync: Fast” (that’s what the option is in nvidia driver control panel) and limiting the fps ingame or control panel.
Advantage: No screentearing and latency very close to Vsync: Off.

Je l’envoie à quelques amis et je le partage également sur delicious. Et bien sûr, merci pour vos efforts.
Bonjour, je voudrais dire que cet article est formidable, bien écrit et qu’il contient presque toutes les informations importantes.
Who uses VSync? Always turn that garbage off.
overexxagerated censorship and anti-spam whatever.
Thanks for being an ignorant and making that dumb decison for so long.
Need it together with adaptive sync (g-sync compatible, freesync) and hdmi 2’s VRR, to eliminate full screen tearing at the bottom of the display.
Blurbusters has it all explained.
blurbusters(.)com/gsync/gsync101-input-lag-tests-and-settings/14/
Of course in some scenarios (e.g. crappy LG W-Oled-TVs who diminish luminisoty big times when switching to gaming mode), the usage of V-Sync: Fast and a fps-limit (ingame or gpu-control panel), might be a better choice.
That way the TV stays in e.g. Filmmaker- or movie mode, keeps all the awesome image quality and features, while the displays is in 120/144 Hz refresh rate mode, without tearing.
Of course it’s not as fluid as adaptive sync or VRR (I already tried plenty).
Cheers to your blog for being a constant reminder that joy is found in the simplest of moments!
