Overclocking made simple: Nvidia RTX cards turn up the heat with a single click

If the idea of overclocking your graphics card is scary, intimidating, or just boring, but you want the improved performance anyway, Nvidia’s new RTX-series of graphics cards may be just what you’re looking for. The new cards will be supported by an application called Nvidia Scanner, which will automatically adjust clock speeds and voltages to get the absolute maximum performance from your card with just a single click.

Historically, graphics card overclocking has been more complicated than CPU overclocking. You needed specialist software or a modified BIOS — and even then it was rarely as easy as just upping the multiplier. Today, it’s much easier, with a number of software tools to make the process more layman-friendly (here’s how we do it), but testing for stability can still be a laborious process. Nvidia’s Scanner is designed to be the next step in that evolution, making it possible to overclock your new RTX GPU to the max, without risking crashes or overheating.

With increased power requirements over their last-generation predecessors, Nvidia’s Founders Edition RTX-series GPUs come equipped with dual-fan coolers for the first time. That extra cooling power means that they should have some extra thermal headroom, and Nvidia claims that it planned to leverage that all along with easy overclocking.

Nvidia Scanner is a big part of that, but it’s not an application — it’s an API that software partners like EVGA and MSI can utilize for their own overclocking tools. According to PC World, Nvidia Scanner is designed to speed up the often slow process of small speed increases in between stability tests. With the press of the Test button, the API will test your graphics card’s ability at different frequencies and voltages, all the way up to its practical maximum. When Scanner starts to detect low-level mathematical errors, it can shut the overclock down before a system crash occurs, making it much easier to avoid hard reboots and system crashes.

This automated overclocking is claimed to take around 20 minutes to complete, but once it’s there, you should have a pretty stable graphics card overclock that you can then fine-tune yourself if you want to push things further or tweak noise levels and power usage.

There are some drawbacks, namely the limitation to core clock increases and the Turing-series of RTX cards. Nvidia is looking to expand into older GPU generations in the future, and may make it possible to use Nvidia Scanner for automated memory overclocking at some point too.

Nvidia DLSS is amazing, but only if you use it the right way
Lies of P on the KTC G42P5.

Nvidia's Deep Learning Super Sampling, or DLSS, has become a cornerstone feature of modern PC games. It started as a way to boost your performance by rendering a game at a lower resolution, but the prominence and popularity of DLSS have prompted Nvidia to add even more features under the name.

Today, DLSS incorporates several different features, all of which leverage AI to boost performance and/or image quality. It can be intimidating if you're a new RTX user, so I'm here to break down all of the increases of DLSS in 2024 and how you can best leverage it in supported games.
The many features of DLSS

Nvidia just made GeForce Now so much better
Playing games with GeForce Now on a laptop.

Nvidia has just added adaptive refresh rates to GeForce Now, its cloud gaming service. The new tech, dubbed Cloud G-Sync, works on PCs with Nvidia GPUs first and foremost , but also on Macs. These include Macs with Apple Silicon, as well as older models with Intel CPUs and AMD GPUs. On the Windows PC side more broadly, Intel and AMD GPUs will not be supported right now. Nvidia has also made one more change to GeForce Now that makes it a lot easier to try out -- it introduced day passes.

Cloud G-Sync's variable refresh rate (VRR) feature will sync your monitor's refresh rate to match the frame rates you're hitting while gaming with GeForce Now. Nvidia's new cloud solution also uses Reflex to lower latency regardless of frame rates. Enabling VRR in GeForce Now should provide a major boost by reducing screen tearing and stuttering, improving the overall gaming experience on PCs and laptops that normally can't keep up with some titles. To pull this off, Nvidia uses its proprietary RTX 4080 SuperPODs.

Nvidia is the ‘GPU cartel,’ says former AMD Radeon manager
A hand holding the RTX 4090 GPU.

AMD's former senior vice president and general manager of Radeon has come out with some strong words against Nvidia. Scott Herkelman called Nvidia "the GPU cartel" in response to a story from the Wall Street Journal in which Nvidia's customers claim that it delays GPU shipments in retaliation for those customers shopping with other suppliers.

The accusation in question comes from Jonathan Ross, CEO of AI chip startup Groq, who said, "a lot of people that we meet with say that if Nvidia were to hear that we were meeting, they would disavow it. The problem is you have to pay Nvidia a year in advance, and you may get your hardware in a year, or it may take longer, and it's, 'Aw shucks, you're buying from someone else, and I guess it's going to take a little longer.'"
