G-Sync and SLI Don't Get Along: Framerate Falls If You Combine Them

Several users have complained lately about performance issues on their SLI systems, and after some discussions in the NVIDIA subreddit and on NVIDIA's forums, the conclusion seems to be clear: performance drops when SLI and G-Sync are working together. The folks over at ExtremeTech have made a good job exploring the issues and they have confirmed that frame rate falls if both features are enabled on the PC. The problem seems related to timing according to their data, but there's no clear solution yet to that issue.

The problems are huge in titles such as Rising Storm 2 (206 vs 75 fps with SLI and G-Sync enabled) and not that important on others like Witcher 3 (113 vs 98 fps). The test setup included two GTX 1080 GPUs and an Acer XB280HK monitor that supports 4K but only at 60 Hz, a perfect choice to detect whether the problem was real or not. In their tests with several games they confirmed the problem, but didn't find a defined pattern: "Turning G-Sync on and using SLI is not guaranteed to tank your frame rate. [...] Different games showed three different performance models". In Deus Ex Mankind Divided the gap appeared only on DX11 mode. In Far Cry 5, the penalty size increases as the frame rate rises, and in Hitman the results were even more confusing.

Remedy Shows The Preliminary Cost of NVIDIA RTX Ray Tracing Effects in Performance

Real time ray tracing won't be cheap. NVIDIA GeForce RTX 20 Series graphics cards are quite expensive, but even with that resources the cost to take advantage of this rendering technique will be high. We didn't know for sure what this cost would be, but the developers at Remedy have shown some preliminary results on that front. This company is working on Control, one of the first games with RTX support, and although they have not provided framerate numbers, what we do know is that the activation of ray tracing imposes a clear impact.

It does at least in these preliminary tests with its Northlight Engine. In an experimental scene with a wet marble floor and a lot of detailed furniture they were able to evaluate the cost of enabling RTX. There is a 9.2 ms performance overhead per frame in total: 2.3 ms to compute shadows; 4.4 ms to compute reflexions; and 2.5 ms for the global denoising lighting. These are not good news for those who enjoy games at 1080p60.

Ace Combat 7: Skies Unknown System Requirements and Performance Revealed

In a continued effort to support the PC platform, BANDAI NAMCO previously announced they would be releasing Ace Combat 7: Skies Unknown on PC. At the time, there was no mention of what the game's system requirements would be. However, thanks to an NVIDIA blog post, we now know not only the game's system requirements but an estimate on system performance as well- at least with their own graphics solutions.

Overall, the minimum and recommended requirements appear to be quite reasonable. BANDAI NAMCO even went so far as to make note that the recommended requirements are representative of what is needed to run the game at the 1920x1080 resolution with max settings. NVIDIA's own testing backs up those claims with the GeForce GTX 1060 offering a comfortable 100 FPS at 1920x1080, and 60 FPS at 2560x1440 resolutions. Meanwhile, those wanting to push the game at 4K will need a GeForce GTX 1080 Ti or better which should offer a steady 60+ FPS.

Benchmarks Find Intel Core i7-7700K Better Than i7-7800X for Gaming

Over at Techspot, Steven Walton managed to get a hold of Intel's new six-core, 12-thread Core i7-7800X CPU, and chose to take it for a spin over a levy of gaming benchmarks. The results don't bode particularly well for Intel's new top i7 offering, though: it is soundly beat by its smaller, svelter brother in virtually all gaming tasks.

Out-of-the-box results are somewhat in line with what we would expect: the Core i7-7700K does bring about a base clock increased by 700 MHz compared to the i7-7800X (4.2 GHz vs 3.5 GHz), and has a higher boost clock to boot (4.5 GHz vs 4 GHz.) And as we've seen over and over again, including with Intel rival AMD's Ryzen offerings, frequency usually trumps core count when it comes to performance when applications are exposed more than four cores. And this leads to Walton's results: the Core i7 7700K is still king in pure FPS terms, coming in with a much more attractive proposition than the 7800X in both minimum and maximum FPS, as well as power consumption.

AMD Community Update: BIOS Updates, Patches, Performance Improvements

Yesterday, we covered how Ryzen's performance has seen a needed lift-up through an upcoming update to Ashes of the Singularity: Escalation. Performance improvements of up to 30% do wonders in bringing up the 8-core, 16-thread Ryzen 7 1800X's performance up to speed with its svelter gaming enemy, the 4-core, 8-thread i/ 7700K. And through a community update, AMD has now shed some light on the ongoing crusade for adapting an entire ecosystem to its Ryzen line of processors architecture features. Case in point: BIOS updates and game patches,

AMD to Roll Out Eyefinity Frame-Pacing Fix in January

AMD is reportedly releasing a fix for frame-pacing issues for Radeon-based systems with Eyefinity setups in January, 2014, according to an AnandTech report. This September, AMD rolled out the first fix into the frame-pacing issues that affected Radeon GPUs based on the Graphics CoreNext architecture, in which raw-framerate didn't come with the right pacing between each frame, resulting in display output that isn't fluid, which even caused accusations to fly from some quarters about how honest AMD really is with performance numbers of its GPUs.

The Catalyst update that rolled out in September 2013 resolved the problem for a majority of users - with single displays connected to single GPUs, but left out cases in which people use Eyefinity (single display head spanning across multiple physical displays), on CrossFireX (multi-GPU) setups. It was originally expected that AMD would release the so-called "phase 2" Catalyst driver update looking into frame-pacing issues this November, but since the month has passed, AMD has obviously hit a delay. AnandTech reports that delay could last as long as two months, and one should expect "phase 2" to come out only towards the later half of January, since in the first half, AMD, along with the rest of the industry, will be busy with the 2014 International CES, where it will launch its next-generation A-Series APUs, codenamed "Kaveri."

AverMedia Intros the Live Gamer HD Gameplay Streaming Solution

AverMedia, specialists in video encoding and archival hardware, introduced the Live Gamer HD addon card. This product solves the problem of gameplay streaming/recording software introducing lag because the software syncs the framerate to match the framerate of the encoded video/stream, not to mention the additional burden on the CPU and hard drive. The addon card acts as an intermediate between the graphics/audio cards and the display/headset, encodes gameplay at resolutions up to full-HD, that's 1920 x 1080 @60 FPS, without affecting the framerate the gamer experiences (the display stream and the recording stream needn't be at sync). The card packs a hardware H.264 encoder, which then works with a software to either stream it online (via streaming services such as Livestream), or records it onto local storage (since it's writing a pre-encoded video, HDD activity will be much lower compared to screencapture programs that write heavy lossless video). AverMedia did not give out pricing information.

HD 7970 Overclocked to 1.26 GHz: 28 nm Tech Really Stretches Its Legs

Welcome to the first TechPowerUp news post of 2012! Read on for a couple of impressive overclocking feats with the HD 7970 graphics card.

It looks like the new AMD Radeon HD 7970 could be a bit of a dark horse and a lot more potent than its stock specifications would suggest - excellent for creating a competitive graphics card market. The reviews at stock speeds show the flagship HD 7970 to be around 10-15% faster than NVIDIA's flagship GTX 580, which doesn't seem all that impressive since the GTX 580 has been on the market for over a year now. However, what the reviews haven't really shown, is what kind of an overclocking monster the HD 7970 is. It definitely looks like AMD could have easily beaten the GTX 580 by a much bigger margin than they did, had they wanted to and it makes one wonder why they didn't.

VR-Zone have spent the New Year weekend overclocking this beast, having reached a whopping 1.26 GHz core clock speed with their HD 7970 - and decent benchmark improvements to go with it. Also, with the fan at 100%, the card never got above a very comfortable 68 degrees centigrade while running Furmark, which is amazing considering how this test is specifically designed to heat a graphics card to the max - but please see the update at the bottom of the article. The stock cooler may be noisy, but it's certainly very effective: an excellent result which will prolong the working life of the card.
