+ | If the video is hideous. | ||
+ | *In 3D games, you can use '''DeSmuME X432R''' as linked below to increase the internal resolution. It can be surprising how detailed DS textures actually are despite the tiny resolution they were made to be played at. This disables the Magnification Filter option, so if you want to use those post-processing effects for 2D games, you have to set it back to native resolution. | ||
+ | *The OpenGL 3.2 renderer option in 3D Settings supports '''Multisampling Anti-Aliasing (MSAA)'''. Turning it on helps the edges of ultra low-res DS polygons and lines smooth out, appear to wobble less during movement, and retain their shape better when viewed from distance. Unlike post-processing effects that modify the still frame after completion and essentially try to guess at the shapes they are smoothing, this effect knows the actual shapes of the polygons themselves. | ||
+ | **Versions before r5032 had this option for a long time, but it was only put in the GUI at r5032. To turn it on in older versions you needed to change a value from false to true in the source code and recompile it. | ||
+ | *Another thing you can do is filter it. Make sure '''OpenGL''' and '''Filter''' are checked under '''Display Method'''. | ||
+ | **If you have an Nvidia card and the OpenGL Display Method is stuttering despite reporting good framerate, open the Nvidia Control Panel and turn off Threaded Optimization for this program. What's happening is sequential OpenGL code is being put on different processors running at different speeds, forcing them to wait for each other repeatedly. | ||
+ | *Finally, there are a variety of post-processing shaders that can be selected under Magnification Filter. Whether that is simple Nearest 2x or some pixel art scaling filter like HQx or xBRZ is up to you. No post-processing smoothing is perfect, but if you want to use one the xBRZ options are generally the most high-end among smoothing filters present. | ||
+ | *OSX version of Desmume also has support for multi-pass post-processing shaders and filters which Windows version currently doesn't have. | ||
+ | *Leaving it native and aligning it to a CRT (Set to a 384 high resolution) is also an option, if you feel like going through the effort. | ||

*SoftRasterizer's texture alignment issues are supposedly fixed on a per game basis with the newer TXT hack. It now seems to be more compatible and showing more effects than GL3.2. Etrian Odyssey and Dragon Quest V seem to work best with it over GL3.2. | *SoftRasterizer's texture alignment issues are supposedly fixed on a per game basis with the newer TXT hack.

− | + | DeSmuME X432R is DeSmuME fork with the option to increase internal resolution. Be warned that this option is very system-intensive. There have been reports of people who can run Dolphin and PCSX2 at a perfect pace but can't run this at full speed using increased internal resolution, however newest versions are far faster. | |
+ | **While generally more accurate, the SoftRasterizer is massively CPU-intensive in this mode, whereas the OpenGL renderer shares the load with your GPU. This can be considered a speedup option, but it also boasts an MSAA option unavailable to SoftRasterizer. | ||
