We used the game's internal resolution scaler on a 4K screen to make the necessary adjustments here. On an RTX 2080 Ti, levels primarily based on sand or snow can run ray tracing at the low setting at 60fps at 1620p resolution, where more reflection-heavy maps like Rotterdam require a 1296p pixel-count to remain locked at the target 60 frames per second. It's difficult to get a lock on how much performance is hit by using DXR, as the computational load changes according to content - there is no flat cost here.
Certain 'fake' god ray effects or a certain type of foliage can also impact performance negatively, sending out far more rays than they should. For example, all levels right now are affected by a bounding box bug making ray tracing more expensive than it should be due to the existence of destructible terrain.
BATTLEFIELD 5 STAT TRACKER CODE
There are plenty of Battlefield 5 DXR performance benchmarks out there right now, and some of the numbers look low - but revised code is forthcoming that addresses a number of issues that should address the most egregious frame-rate drops. A video breakdown of Battlefield 5 on PC, including key visual features, RTX features and console comparisons. So, the clarity of reflections reduces as you go down the settings chain but just to stress again, even the low setting is still giving you a proper ray traced experience, with the most important surfaces like water, mirrors and polished metals reacting as they should to the surrounding environments. Ultra is at 40 per cent resolution, high at 31.6 per cent, medium at 23.3 per cent and low at 15.5 per cent. If an area needs fewer rays, it reduces the size of the box, but on the other hand, if the entire screen is filled with reflective water, it places a limit proportionate to resolution. Battlefield 5 shoots out a variable amount of rays by binning and culling the ray count based on dividing the screen into 16x16 pixel boxes. Another hit comes from the resolution of the reflections themselves. Generally, the quality still holds up, though it's just a little sad to see the view weapon losing the immediate surroundings' colours and tones disappear. The roughness cut-off of material receiving ray traced reflections is raised, resulting in duller materials, painted metals or wood surfaces receiving cubemap textures instead of ray traced reflection. The medium setting is where the biggest compromises to ray tracing quality begin to become evident. But what actually happens to the quality of ray tracing as you move down the various settings?
DICE's recommendation right now is to run the DXR setting at low for performance reasons, and this still looks great.
BATTLEFIELD 5 STAT TRACKER PC
First up though, it's worth taking a look at the Battlefield 5 PC tech analysis video embedded below - principally to get a look at the game running in real-time in its day one incarnation and to get a sense of how ray tracing scales across the four available presets: low, medium, high and ultra. In fact, at the end of our analysis piece, you'll find our in-depth interview with DICE rendering engineer Yasin Uludağ, who has been working with colleague Johannes Deligiannis for the last year on implementing ray tracing within Battlefield 5. Real-time ray tracing remains massively expensive from a computational perspective, performance isn't completely ideal - but this is emergent tech, optimisations are coming, and having spoken to DICE directly, we know what kind of strategies the developer is pursuing to push frame-rates higher.
BATTLEFIELD 5 STAT TRACKER PATCH
But alongside the revolution in visuals is the reality of the implementation - this is an alpha patch running on first-gen hardware. It's a watershed moment in many ways and a phenomenal technological achievement - not just from the RTX hardware that makes it possible, but also from the engineers at DICE who committed to ray tracing in all of its shiny, real-time reflection glory.
Battlefield 5 has shipped on PC, accompanied by our first look at a revolution in gaming graphics - real-time ray tracing via Nvidia's new RTX line of GPUs.
