Gameplay Performance Continued

Cyberpunk 2077

Cyberpunk 2077 was released in December 2020 and uses the REDengine 4. We have the game patched to version 1.61 and perform a long manual run-through driving in the game’s open world. We test using the Graphics Preset option to set graphics settings, mainly “Ultra”.  This game supports DLSS and FSR.

In Cyberpunk 2077 we are running at 4K and “Ultra” settings above, the Radeon RX 7900 XTX is 3% faster with SAM ON and the Radeon RX 7900 XT is almost identical. With FSR2 the Radeon RX 7900 XTX is 2% faster with SAM ON and the Radeon RX 7900 XT with FSR2 is almost identical.

With Ultra Ray Tracing turned on at 4K the results are identical on both video cards in Cyberpunk 2077. There is a little difference with FSR2 on the Radeon RX 7900 XTX, but not much here, let’s see what 1440p does.

We actually do see larger results at 1440p, here the Radeon RX 7900 XTX is 5% faster with SAM ON and the Radeon RX 7900 XT is also 5% faster with SAM ON.

With Ray Tracing on at 1440p the Radeon RX 7900 XTX is 3% faster with SAM ON but the Radeon RX 7900 XT is much closer together with Ray Tracing.

Watch Dogs Legion

Watch Dogs Legion was released on the PC in October of 2020 and uses the Disrupt game engine. We utilize the built-in benchmark for testing. We have the HD Texture pack installed and enabled for testing. We use the built-in graphics preset of “Ultra” for testing. This game supports DLSS upscaling.

With Ray Tracing at 1440p we see the biggest results yet here, 15% faster with SAM ON on the Radeon RX 7900 XTX and 16% faster with SAM ON on the Radeon RX 7900 XT! That is significant and will change how video cards lineup with each other.

Metro Exodus Enhanced

Metro Exodus Enhanced is being run with Shading Quality at “Extreme” and Ray Tracing at “Ultra.”  This is a demanding game, that heavily focuses on Ray Tracing utilization, including Global Illumination.  We are utilizing the built-in benchmark.
