When you see FSR, you need to stop thinking "technology to improve performance" and start thinking "upscaling filter", because that's all it is. All this talk about the emulator being CPU-limited is silly-of course it's CPU limited, but what's your point? This was never going to change or address that. It's simply to improve the look of PlayStation 3 games, which generally run at sub-HD resolutions. The only reason that they are marketed as increasing performance is because they are usually used along with a sharp reduction in render resolution, usually done silently by the game engine, which is misleading in my opinion.Įnabling FSR on RPCS3 isn't for the purpose of increasing performance. You guys keep talking about this technology as if it's something that increases performance.
AMD GPUs also fall under this due to Xenia triggering driver bugs causing crashes when its ROV-based rendering path is used.The comments on this article are weird. Integrated GPUs will also generally provide too low frame rates for comfortable playing. "GPUs without ROV (rasterizer-ordered view) / fragment shader interlock support will perform worse and possibly have more graphical issues. However, this is a hardware feature, and thus on older graphics cards, Xenia is limited to the RT path." This allows for much higher performance since there's no expensive data copying, and better accuracy because of no pixel format limitations. § What is ROV? "Using the Rasterizer-Ordered Views (ROV) feature of Direct3D 12 allows Xenia to overcome by doing blending and depth/stencil testing manually in pixel shaders, rendering directly to the 10 MB buffer. Leaving No Pixel Behind: New Render Target Cache, 3x3 Resolution Scaling & Three Years in Xenia’s GPU Emulation.
The demo mode and full game files for XBLA titles are actually identical, and this option allows the games to exit demo mode. If you are trying to emulate Xbox Live Arcade titles then the line "license_mask = 0" should be changed to "license_mask = 1". GPU options such as v-sync, resolution scale, and much more can be found in the file. The file can be opened and edited with any text editor without having to change the file extension and can be found under the filepath ".\Users\User\Documents\Xenia" along with shader cache and per-game files when using windows. Most configuration options usually found in GUI are instead found in the file. GPU: Any capable of Vulkan or Direct3D 12 (Check from this list.).CPU: Any capable of AVX(2) (Check with CPU-Z.).AMD supports it with Radeon Vega but has driver issues.) (Nvidia GeForce GTX 950 or better, GTX 965M for laptops. GPU: Any capable of Direct3D 12's Rasterizer-Ordered Views.CPU: Any 4th-gen Intel processor capable of AVX2 or newer.Xenia is capable of 3x3 upscaling, but such a feature is resource intensive and can only be accomplished with high-end GPUs at the moment. Triang3l also built a different, faster and more accurate memory emulation, which should lead to less broken vertices and textures being seen in-game.įor proper handling of the GPU's capabilities, Xenia now requires a specific feature of Direct3D 12 called Rasterizer-Ordered Views which is limited only to newer cards. Once implemented, it more than doubled performance.
Up until 2018, progress continued steadily until the developers hit a roadblock in accurately emulating Xenos, the GPU of the Xbox 360.įor the next three years, an active contributor named Triang3l completely rewrote the GPU implementation with the primary goal of addressing this.
It was the first emulator to run a commercial Xbox 360 game, Frogger 2. Xenia originally began development in early 2013 as a side project by Ben Vanik.
