Update 12: Ray-Tracing and DLSS – No Speed Loss?<\/h3>\n
\n

Computerbase.de (external link)<\/a> has produced yet another intriguing article on the topic of Ray-Tracing. The specialist publication refers to a report originally produced by VideoCardz.com, a well-established source for everything related to the world of graphics cards. This usually reliable source hints at Battlefield V being one of the few games that will support both ray-tracing and the soon to arrive NVIDIA Turing feature known as DLSS<\/em>. This could potentially result in the GeForce RTX 2080 Ti<\/strong> being able to achieve similar FPS performance levels to when RT is deactivated. <\/p>\n

The GeForce RTX 2080 Ti<\/strong> and its fellow travellers in the GeForce RTX series of graphics cards that are based on the Turing architecture combine three kinds of computational units in a single chip: CUDA shaders, ray-tracing cores and Tensor cores. CUDA Cores are the CUs with which most of us are traditionally familiar, with their capacity for rapid pixel calculations, while the others are relative newcomers used almost exclusively for the realistic calculation of real-time lighting and shadow effects. <\/p>\n

These kinds of effects used to require, with more traditional rendering methods, a massive amount of GPU horsepower. Ray-tracing is the go-to tool, for example, in Hollywood blockbusters where scenes may require days of rendering time in order to achieve the desired level of realism. RT cores, which are specially designed to forge ahead in such applications, makes real-time ray-tracing into a reality. As such, a PC equipped with a powerful graphics card like the GeForce RTX 2080 Ti<\/strong> will be able to provide PC games with ray-tracing support to unlock unparalleled realism and performance. <\/p>\n

Then we come to the second type of compute cores, namely: Tensor Cores. The power of these cores was originally harnessed in the form of the Volta architecture, specially designed to assist in Deep Learning and AI-related tasks. These use a specialised matrix with data lines that are optimised for Floating Point performance. Turing graphics cards use an optimised version of the original Volta cores. The task of these cores is to enable graphical acceleration by means of “learning”. <\/p>\n

Deep Learning Super Sampling (DLSS)<\/em> is an anti-aliasing tool whereby the GPU is trained to form sharper images. DLSS also enables rendering at speeds of up to twice those of earlier rendering methods. DLSS is then combined with ray-tracing in order to minimise the loss of Frames per Second (FPS) when the additional lighting and shadow effect calculations are factored in. The ability to compensate for the extra load is possible due to the power of NVIDIA’s Tensor Core technology. In Battlefield V for instance, this means that a GeForce RTX 2080 Ti<\/strong> is capable of achieving a similar FPS with ray-tracing and DLSS activated as when neither of these Turing features are applied.<\/p>\n

Update 11: DXR Update Accelerates Ray Tracing Up to 50%<\/h3>\n
\n

Until now Battlefield V<\/em> has been one of the few games to support ray tracing. As shown in early tests, this new feature on GeForce RTX 2000-series graphics cards costs a lot in terms of performance, and so ray tracing has gained little traction thus far. Yet this could now change, due to NVIDIA and games developer DICE chipping away at the challenge of optimising ray tracing performance. <\/p>\n

Computerbase.de (external link)<\/a> and wccftech.com (external link)<\/a> have both been busily engaged in keeping up with the subject. What seems to be responsible for the optimisation is a combination of three different components: an update to DXR drivers, an update to graphics card drivers, as well as a patch to Battlefield V itself. <\/p>\n

Computerbase.de has consequently been able to show significant improvements to ray tracing performance on the GeForce RTX 2080<\/strong> at Full-HD (1.920 x 1.080p) with DXR Ultra in Battlefield V’s multiplayer mode, producing an average of 87,1 FPS compared to just 68,2 FPS previously. This corresponds to an increase of a respectable 27 percent. With a resolution of 2.560 x 1440p and DXR Ultra activated, average FPS has gone from 48,2 to 68,5, making for an impressive performance increase of 41 percent. In the single player campagne, the RTX 2080<\/strong> demonstrated increases of up to 80 percent! <\/p>\n

Here is a video from NVIDIA’s GeForce division on the DXR DEV Update: <\/p>\n

wccftech.com has also reported on the update for the drivers and the games patches. The DXR filter settings and optimisations also include a new „denoiser“. A bug was also apparently removed, one that led to stuttering and hitching in RTX performance. Ray tracing isn’t the only thing games devs are working on right now however, more and more frequently they are adding RTX graphics cards’ features into the latest PC games. <\/p>\n

Thanks to NVIDIA’s Adaptive Shading feature (NAS) the performance in Wolfenstein II has already seen moderate improvements. NAS also deploys the power of NVIDIA’s Tensor Cores. What influence Tensor Cores have on ray tracing performance exactly remains somewhat unclear. The Tensor Cores are as new in the world of deep learning as they are in gaming graphics cards.

Update 10: der8auer Video on RMA Rates of the RTX 2080 Ti<\/h3>\n
\n

The Geforce RTX 2080 Ti graphics card<\/strong> has now been in circulation for a while. The fastest gaming graphics card ever may possibly be suffering from some issues however. There have been some rumours about the RMA rates of the NVIDIA GeForce RTX 2080 Ti<\/strong> being relatively high on the Founders Edition. Are these rumours true? If they are, does the issue affect custom AiB partner graphics cards too? Roman „der8auer“ Hartung has looked into the figures on RMAs and drawn some interesting conclusions. More available in the following video: <\/p>\n

Update 9: King Mod GeForce RTX 2080 Ti with Pre-Installed Water Cooler<\/h3>\n
\n

The King Mod GeForce RTX 2080 Ti graphics card with pre-installed watercooler <\/strong> allows users to enjoy the full unlocked power of the Turing architecture. The graphics cards are equipped with GPU watercooling courtesy of our King Mod Service experts, enabling them to be integrated into a custom loop with ease. <\/p>\n

The special thing about King Mod graphics cards with pre-installed watercoolers however, is the fact that they are guaranteed. Those who wish to put a cooler on an RTX 2080 Ti themselves will find they invalidate the manufacturer’s guarantee. As a result, should something go wrong with the modification, you have generally lost the money you invested. <\/p>\n

The modding experts of the King Mod Service offer a special service as a result: when you order your PC, swap out the graphics card for watercooling and retain the full manufacturer’s guarantee. The cards are fully pre-tested prior to installation where they pass a benchmark. The customer thus receives a fully functioning graphics card with a perfectly mounted cooler. <\/p>\n

Update 8: OC World Record with the GeForce RTX 2080 Ti – Video from der8auer<\/h3>\n
\n

On the internet, multiple tech Youtubers have been involved in an overclocking competition. The aim was to achieve the highest possible score in a dual-GPU system in Time Spy Extreme and Cinebench from 3DMark. The team from Gamers Nexus (external link)<\/a> used radiators cooled in ice water to catapult themselves to the top of the leaderboards, while Jay from JayzTwoCents (external link)<\/a> used an air conditioner to cool his hardware. Paul from Paul’s Hardware (external link)<\/a> and LTT Linus Tech Tips (external link)<\/a> also used air cooling to take a shot at the record – auch if Linus and his team ended up breaking the wrong record. Kyle from Bitwit (external link)<\/a> combined multiple cooling solutions, although he had to cancel his attempts due to defective hardware. <\/p>\n

Here are the YouTubers’ results as they stand (08.10.2018):<\/p>\n
