![]() ![]() It was one of the first generations of 3D chips, with only a fixed pipeline. The renderer is the emulator component that emulates the Dreamcast/Naomi GPU chip, namely the PowerVR Series2. Update your core later today to get the latest version with the Vulkan renderer! Available for Android, Windows, and Linux.įor more information, read down below… Wait … a new what? Completely open-source, written from scratch, and available later today on RetroArch. The first Dreamcast emulator ever to get a Vulkan renderer. Blog, Dreamcast, Flycast, RetroArch Flycast world’s first Dreamcast emulator to receive Vulkan renderer – available later today on RetroArch with nightly core! It will then download and install this core. Start up RetroArch first –Ī – If you have already installed the core before, you can go to Online Updater and select ‘Update Installed Cores’.ī – If you haven’t installed the core yet, go to Online Updater, ‘Core Updater’, and select ‘Flycast’ from the list. There are two ways to update your Flycast core. ![]() Hopefully both renderers can be at feature parity soon in these departments. Neither can we show a similar picture on Vulkan right now because the aforementioned PVR2 postprocessing filters are not available there. NOTE: Because this is the OpenGL renderer, anisotropic filtering right now is not available, so we cannot show you a picture of how the PVR2 postprocessing looks like in conjunction with 16x AF. Here we have mip-mapping enabled and PowerVR 2 Postprocessing filter enabled. Soul Calibur on Dreamcast with mip-mapping enabled and PowerVR postprocessing filter NOTE: For now, the PowerVR postprocessing filters only work with OpenGL. You can also take advantage of leilei’s PowerVR post processing filters on top to further enhance the authenticity of the picture. You don’t have to stop at mipmapping and AF filtering of course. Even further tweaking possible with PowerVR postprocessing filter While you can still make out some of the far textures in the distance being slightly blurry as a result of the mip-mapping, overall the blurriness factor is significantly reduced as a result of the agressive 16x AF filtering being applied here, even at a very low resolution of 640×480. Soul Calibur on Dreamcast with mip-mapping enabled and 16 x AF filtering The Vulkan renderer allows you to apply Anisotropic filtering (AF) to the textures (to learn more about it, read the Wikipedia page here). ![]() Combining mip-mapping with anisotropic filtering The picture down below shows Soul Calibur running with mip-mapping enabled: Soul Calibur on Dreamcast with mip-mapping enabledĪt higher resolutions you will notice the blurriness starting to gradually disappear. The picture down below shows Soul Calibur running with mip-mapping disabled: Soul Calibur on Dreamcast with mip-mapping disabled To best illustrate the effect mip-mapping has on the video output quality, let us show some comparison pictures at the Dreamcast’s native 640×480 resolution. See the picture down below how the title screen above for instance looks like now – NFL 2K2 – texture bleeding issues fixed How mip-mapping looks like on Dreamcast Many of these issues have now been fixed. To learn more about texture bleeding, you can read this StackExchange article here.Īnother example of what texture bleeding looks like can be seen down below (and note that this is now also fixed) – previously texture bleeding would regularly occur at upscaled resolutions – NFL 2K2 – texture bleeding issue when upscaling – how it looked before This caused issues with games like Railroad Tycoon 2 where the beach texture was not properly displayed.īefore the fix, you’d have weird magenta colors on the beaches with the Vulkan renderer. What happened before is that these auto-generated mipmaps would ‘bleed’, whereas the ones provided by the game do not. The Vulkan renderer no longer auto-generates mip-maps and instead uses the proper mipmap levels. Second, all texture mipmap levels are now uploaded to the GPU. Some significant improvements have been made to the Dreamcast emulator core Flycast by flyinghead that serve to increase the graphics accuracy.įor one, the OpenGL renderer has mip-mapping support now for the first time. ![]()
