Microsoft DirectX Ray Tracing (DXR) is part of DirectX 12. NVIDIA RTX technologies include both DXR Ray Tracing and Deep Learning Super Sampling anti aliasing (DLSS). BFV currently does not support the DLSS function. The first game to support NVIDIA’s RTX DXR Ray Tracing technology has finally been released for gamers with Battlefield V. In addition, there has been a recent very large performance patch which significantly improves the performance of DXR Ray Tracing reflections in this game under NVIDIA RTX video cards. Claims of up to 50% performance advantages were made.
While we do not have the tools needed to actually "count" the rays being cast, it however looks like NVIDIA is now casting way less rays than in the previous version, and the ray traced reflections are dynamically being turned off when there is fast motion, and re-enabled with the motion slows back down (especially for screen space reflections). So we think that NVIDIA's "50% performance improvement" is being realized through the GPU simply doing less DXR work, instead of this being a "magical" performance patch.
In our performance review today, we are going to focus on one video card, the NVIDIA GeForce RTX 2070. We are going to follow up with the RTX 2080 and RTX 2080 Ti articles as well. We are using an ASUS ROG STRIX GeForce RTX 2070 OC video card. We will be playing real games of Battlefield V using the newest patch which "improves" DXR Ray Tracing reflection performance. We are going to find out if the GeForce RTX 2070 has the muscle to allow a playable experience in multiplayer BFV with DXR Ray Tracing reflections enabled.
Before we begin our look at Battlefield V performance we need to clarify and define some terminologies. First it is important to understand that DXR (which stands for Microsoft DirectX Ray Tracing) is inherent to Microsoft’s DirectX. It is tied into DirectX 12 and anytime you hear DXR it refers to the API or game supporting Microsoft Ray Tracing in the API. It only runs under DX12. DXR does not have anything to do with NVIDIA specifically. It is a game feature you can toggle on or off if there is hardware support when/if we see hardware support from either AMD or Intel.
NVIDIA RTX branded video cards need only support either DLSS or reflections ray tracing in a game for NVIDIA to refer to it as an "RTX enabled" video game currently. As it stands now, BFV and the Final Fantasy XV benchmark are the only two games supporting any of these features.
The video below shows where exactly you should expect to see ray tracing used in BFV.
