"Our final game focus is the big one - Red Dead Redemption 2. Stadia is based on a Linux OS running the Vulkan graphics API, and we know from our recent PC testing that Rockstar supports both this and DirectX 12 with the latest iteration of the Rage engine. We also know that invoking the PC game's higher-end features comes at a cost, so the developer's choices here in how to use Stadia's power should be intriguing.
Again, the obvious takeaway from Stadia is that despite a 4K output from Chromecast Ultra, the game itself is rendering at a lower resolution. It took a bit of effort to figure out what's going on, but the evidence points to Red Dead Redemption 2 operating with an internal pixel-count of 1440p. Again, we'll be looking at the specific visual feature set of the Stadia port in future, but first impressions suggest a good level of similarity in terms of specific settings with the Xbox One X version. Meanwhile, the Stadia port of RDR2 also seems to be running at the same 30 frames per second frame-rate as well. It's Red Dead Redemption 2 in its entirety, it plays well, and even with the existing, very large latency built into the game, there are no issues whatsoever in progressing through the game via the streaming platform."
My thought to this
Stadia raw performance should be around 80% faster than Xbox One X (10,7 TFLOPS Vega 56 VS 6 TFLOPS Polaris 580 ) , in realities it's running at 44% of the total pixel count with the same graphical settings and framerate.
Just for clarification Read Dead Redemption 2 on Xbox One run at 4k native at 30fps .
It will be even worse if we include streaming video compression (Youtube Video compression) and latency problem on average connection.
