Battlefield V NVIDIA Ray Tracing RTX 2080 Ti Performance

How many frames will NVIDIA Ray Tracing cost you in Battlefield V with the RTX 2080 Ti? We take an ASUS ROG STRIX RTX 2080 Ti OC and turn on NVIDIA Ray Tracing in BFV Multiplayer at 1080p, 1440p, and 4K to find out. We test VRAM capacity, which reveals something very important that can impact NVIDIA Ray Tracing performance.


VRAM Utilization Testing

There is one aspect of GPU testing we have left for the last. However, we have discovered that it is extremely important, and this is a topic that you will want to pay attention to.

We wanted to wait until the last video card, the GeForce RTX 2080 Ti, to test VRAM utilization in BFV with and without DXR because it has the most VRAM on board, 11GB. This will allow us to test each resolution, and "Low" and "Ultra" DXR quality settings with DX11 and DX12 with un-restrained VRAM capacity. In this way we can see the maximum amount of VRAM DXR can consume while gaming.

To get these results we actually played real-world 64-play multiplayer matches in Rotterdam for 20-minute sessions, and recorded the maximum VRAM capacity used. We restarted the system between each test.

The first thing to note is the DX11 NO DXR VRAM results at 1080p, 1440p and 4K. This is the fastest performance in the game, and does not have DXR enabled. In all situations of DX11 with NO DXR VRAM utilization only reaches a maximum of 6GB at 4K. At 1440p it’s above 4GB, but nowhere near 8GB. At 1080p it is still above 4GB slightly, but nowhere near 8GB. This means 8GB video cards will do well in DX11 with NO DXR in this game. However, 4GB video cards are not enough even at 1080p in this new game, as it can exceed 4GB of VRAM at 1080p.

Now look what happens when we simply enable DX12 with NO DXR. The VRAM capacity utilization jumps way up when DX12 is enabled at every resolution. At 1080p it is hitting 7340MB and at 1440p it hits 7976MB, nearly a complete 8GB of VRAM just at 1440p with DX12 enabled and NO DXR. This means 8GB video cards will be hitting their limit just enabling DX12. At 4K 8GB is exceeded as it consumes 9504MB of VRAM! 8GB is definitely not enough for 4K with just DX12 enabled and no DXR.

Now look at how much turning on just the lowest "LOW" DXR setting consumes at each resolution. At 1080p it adds another 400MB and rises to 7740MB. At 1440p it adds 710MB and now exceeds 8GB of VRAM at 8686MB. This means even at just "LOW" DXR 8GB video cards will be bottlenecked at 1440p with "LOW" DXR. At 4K it consumes another 1674MB and now hits the limit of this very video card we are using, 11GB of VRAM! That’s just "LOW" DXR!

Now it is time to take it to the highest level, look at the "ULTRA" DXR VRAM results. Even at just 1080p 8GB of VRAM is exceeded with 8559MB total usage. That means an 8GB video card will be bottlenecked at 1080p with "ULTRA" DXR enabled. At 1440p 8GB is of course still exceeded reaching 8824MB. 4K is just bonkers, we are hitting the limit of this video card at 11229MB and there is no telling how much it can actually consume. We’d need a video card with more than 11GB of VRAM just to see what "ULTRA" DXR at 4K can really consume in total. Let’s talk about all of this in the conclusion on the next page.

We also looked at system RAM while testing. The highest system RAM utilization was around 11-12GB out of our 16GB while gaming. Therefore, we were not bottlenecked by system RAM. As long as you have 16GB of system RAM you should be fine.
