Ray tracing and DLSS/FSR performance:
Let’s now take a look at the four games we have selected that support Ray Tracing and DLSS. This will allow us to judge the impact of these two technologies on FPS. As you can see, some games support first generation DLSS and others support 2.0. We have also added Far Cry 6 which supports DirectX Ray Tracing and AMD’s SFR but is still compatible with NVIDIA graphics cards. The four DirectX 12 games we will be testing with Ray Tracing or DirectX Ray Tracing and DLSS or SFR are :
- Shadow of the Tomb Raider
- Watch Dogs: Legion
- Metro Exodus PC Enhanced Edition
- Far Cry 6
As in the previous tests, we will opt for a 2160p resolution for the use of Ray Tracing. Why do we do this? Simply because it allows us to be aware of the contribution of DLSS when FPS drops with the use of Ray Tracing.
Shadow of the Tomb Raider:
The first one we’re adding to this comparison that supports Ray Tracing and DLSS 1.0. Three levels of Ray Tracing are offered in the game (medium – high – ultra) and only one level of DLSS. For our benchmarks, we opted for Ultra graphics quality, ” ultra ” Ray Tracing and DLSS enabled.
Even with Ray Tracing enabled, our RTX 3090 Ti performs perfectly with an average of 68 FPS. Enabling DLSS gives a frame rate boost to 93 FPS at 2160p.
Watch Dogs Legion:
The second game, Watch Dogs Legion, supports Ray Tracing and DLSS 2.0. It is one of the most demanding games of the moment. Three levels of Ray Tracing are offered in the game (medium – high – ultra) and four levels of DLSS (performance – quality – balanced – ultra performance). For our benchmarks, we opted for Ultra graphics quality, “high” Ray Tracing and “balanced” DLSS.
The Ray Tracing in Watch Dogs Legion makes all the cards suffer, including our RTX 3090 Ti! As a reminder, we were getting an average of 90 FPS which drops to 47 when Ray Tracing is activated. Fortunately, DLSS in “balanced” mode comes to the rescue and raises this average to 85 FPS.
Metro Exodus PC Enhanced Edition:
Third game and supports DLSS 2.0. We have devoted a report to it. Three levels of Ray Tracing are offered in the game and four levels of DLSS (performance – quality – balanced – ultra performance). For our benchmarks, we opted for Ultra graphics quality, ‘ high ‘ Ray Tracing and ‘ quality ‘ DLSS.
Once again, the combination of Ray Tracing and DLSS gave our sample of the day an average of 46.3 FPS at 2160p. The use of DLSS will allow our current sample to go well over the 60 FPS mark with an average of 75.9 FPS.
Far Cry 6:
The latest game we are adding to this section as it supports DXR as well as the SFR offered by AMD. For our benchmarks, we chose Ultra graphics quality, we enabled both DRX and FSR in ” quality ” mode for all three resolutions: 1080p, 1440p and 2160p. 
This is a visual change in our graphics, since here, with FSR, both NVIDIA and AMD cards can benefit from this FPS gain. In Far Cry 6, our RTX 3090 Ti gets an average of 77 FPS with Ray Tracing enabled. As a reminder, without Ray Tracking, the average was 91 FPS. FSR brings a gain that pushes this average to 108 FPS.
