That instantaneous loading is the source of all our problems. There is no preloading of the TEV configurations whatsoever, since the TEV unit doesn't have the memory for that. Unfortunately for us though, the TEV unit is designed for the game to configure and run TEV configurations immediately when an effect is needed. In fact, the TEV unit has very similar capabilities to the DirectX 8 pixel shaders of the Xbox! It was so flexible and powerful that Flipper was reused as the Wii GPU (redubbed Hollywood) with few modifications. While it has some fixed-function parts, Flipper features a programmable TEV (Texture EnVironment) unit that can be configured to perform a huge variety of effects and rendering techniques - much the same way that pixel shaders do. Flipper, the GameCube GPU, is the latter. This is especially important on older consoles, which may not have enough memory for or possibly even the capability to store shaders in memory. When you know the precise hardware you are going to run the game on, and you know that the hardware will never change, you can pre-compile GPU programs and just include them on the disc, giving your game faster load times and more consistent performance.

Due to the number of different PC GPUs out there, it's impossible for PC games to pre-compile their shaders for a specific GPU, and the only way to get shaders to run on specific PC hardware is for the video drivers to compile at some point in the game.įlipper, the GameCube GPU, is the largest chip on the motherboard. This compiling takes processing power and time to complete, so modern PC games usually get around this by compiling shaders during periods in which framerate doesn't matter, such as loadtimes.

Devs write code in a shader language from an API (such as OpenGL) and a shader compiler in the video driver translates that code into binaries that your PC's GPU can run. To unlock this power, developers use shaders - programs that the GPU runs just like a CPU runs an application - to program the GPU to perform effects and complex rendering techniques. Modern GPUs are incredibly flexible, but this flexibility comes at a cost - they are insanely complicated.

All in an effort to emulate the full range of the GameCube/Wii's proto-programmable pipeline without falling victim to this pesky stuttering. A journey that would take multiple GPU engineers across two years. That hope is what fueled an arduous journey against seemingly impossible odds. A theory that would take hundreds, if not thousands, of person-hours just to see if it was possible. It started out as a theory that had a chance of working. Despite this, some still privately held onto a glimmer of hope. Ironically, we hated the stuttering as much as anyone else, but the sheer insanity of the task was enough to keep most developers away. It was something that was deemed unfixable and was garnering a lot of ill will and frustration within the community. There was some frustration and even antipathy from the developers toward shader compilation stuttering. While some of this may be partially due to increased GPU requirements from integer math, the bigger cause was actually that the stuttering stuck out more with there now being fewer serious issues otherwise. Since the release of Dolphin 4.0, users have actually complained about shader compilation stuttering at an increasing rate even. Though emulation has improved to near perfection in many titles, the stuttering has remained the same over the years. When games barely ran at all, a little stutter here and there wasn't a big deal. This problem has been a part of Dolphin since the very beginning, but has only recently become more of a focus. The slowdown when loading new areas, effects, models, and more is commonly referred to as "Shader Compilation Stuttering," by users and developers alike. Yet, every time you go to a new area, or load a new effect, there's a very slight but noticeable "stutter." You turn off the framelimiter to check and your computer can run the game at well over full speed. The game is running full speed, there are no graphical glitches, and you can use your favorite controller if you want. When you're playing your favorite game on Dolphin with a powerful computer, things should run fairly well.
