CEMU is a Wii U emulator made by two developers. It is a closed source project, so no outside commits are made to the piece of software. But, it still surprises me, the rate at which this emulator improved is remarkable, to say the least. It wasn’t very long after it’s the initial release that we were getting games to run and now the emulator has reached new heights. You can now emulate The Legend Of Zelda: Wind Waker on Integrated GPU’s.
A youtube user going by the name of MiXobit has posted a video where he runs The Legend of Zelda: Wind Waker on an Intel Integrated Intel GPU. The game seems to run at 720P resolution and a rock solid 30fps. The CPU is not being utilized fully which indicates the GPU is holding it back, which is to be expected in this case, no surprises there.
The Integrated GPU in question here is the HD 630 that comes in the Intel I5 8400 CPU. Granted emulators are somewhat more CPU dependant rather than GPU dependent. The CPU is also 6 core with a remarkably good single and multi-thread performance. Still, not even running but rather emulating this game on Integrated Graphics is amazing nevertheless.
What’s even more astonishing is that just two developers achieved this. Emulators like PCSX2 and Dolphin that emulate the PlayStation 2 and Wii, on the pc respectively, took years to be able to even run games stable playable state. These two emulators have only gotten >50% of the total games at playable state in recent years. Compare that to how fast CEMU has developed just makes you appreciate the developers even more.
This fast rate of improvement in emulation performance might be because of new graphics APIs like DirectX 12 and Vulkan that are more efficient and better. These graphics APIs just make better use of modern hardware like using all of the multiple CPU cores on your processor. Another contributing aspect to this is that modern hardware has gotten considerably faster. Everyone is rocking a decent Quad Core CPU at least with many gamers having PC configurations that cross even that, going up to 6, 8, and even 12 cores with multiple threads. Even Integrated GPUs of today aren’t the worst. You could even play Fortnite on Intel’s latest Integrated GPUs, granted at potato settings.
