The AMD Driver Updates and OpenGL Performance
Recently, we got some driver updates from AMD which have significantly improved the open GL performance on these APUs. This is a bit of a hit or miss scenario, but overall, we're seeing much better performance with many games. One specific example is Bayonetta 2 at 1080p Vulcan back in, where we were able to achieve a 15 watt TVP. This level of performance was previously only seen on the Wii U using the simu emulator.
However, it's worth noting that we can still experience some limitations when it comes to scaling up certain games. For instance, Breath of the Wild at 720p pulled up to 30 watts in some cases. While it's possible to lower the resolution and graphic settings to get a smoother performance, 720p seems like a sweet spot for this game, and it's definitely playable. But again, we'll need to push that TDP up next time.
Next Up: Original Xbox Emulation using Cxbx Reloaded
We've also been testing out original Xbox emulation using cxbx reloaded, and while it has its issues. We experienced some black screen issues and sound cutting out, which seems to be related to the newer Radeon drivers not being fully compatible with the latest version of cxbx. Fortunately, this is an ongoing issue that can be fixed as new updates become available.
One of the most impressive aspects of Xbox 360 emulation using Zenia, however, is the significant performance improvements we've seen in recent months. Six months ago, it was virtually impossible to run games at anything close to 60 FPS on this APU. But with the Canary build of Zenia, we're now seeing frame rates that were previously unimaginable. Take Forspaw 2, for example – running at 60 FPS is a truly impressive achievement.
However, when it comes to more demanding titles like After Burner, we do need to push up that TDP to get the performance we want. In this case, we're seeing around 30 Watts, which is definitely needed to maintain smooth gameplay.
PS3 Emulation using RPCS3
Moving on to PS3 emulation using rpcs3, Vulcan has been handling it remarkably well. We've seen consistent performance at 15 watts for easier-to-emulate titles like Ninja Gaiden and Demon Souls. These games are running smoothly and without any issues – it's a great sign that we're on the right track.
However, as with any emulator, there are some limitations to keep in mind. For instance, certain harder-to-emulate games like Skate 3 or God of War 3 require more power than others. In these cases, we need to push up that TDP to get them running smoothly. But for the most part, rpcs3 has been handling PS3 emulation with ease.
PS3 Emulation on the io2 – A Great Experience
One thing that's become clear is that the io2 handles emulation remarkably well. Whether it's cxbx reloaded, Zenia, or rpcs3, this device can handle a wide range of games and emulators without any issues. It's definitely an impressive piece of hardware.
Of course, as with any handheld, there are some trade-offs to consider. We do need to push up that TDP to get the performance we want out of certain games. But overall, the io2 has proven itself to be a powerful and capable device when it comes to emulation.
Additional Features – 40 Gig USB 4
One feature worth mentioning is the io2's support for 40 gig USB 4. This means that users can connect an external GPU (eGPU) if desired. In fact, we've created a video showcasing some performance with an eGPU attached – it's definitely worth checking out.
While this does mean that the io2 could potentially become a full-fledged gaming PC, its primary function as a handheld is still intact. However, for those interested in exploring more advanced features like eGPU support, there's certainly potential here.
Conclusion
Overall, we've been impressed with the io2's performance on various emulators and games. From cxbx reloaded to rpcs3, this device has proven itself to be a capable and powerful handheld. While there are some limitations to keep in mind, such as the need to push up that TDP for certain games, the io2 is definitely worth considering for anyone interested in emulation or gaming on-the-go.
And with its upcoming features like Steam OS installation and eGPU support, the potential for this device goes far beyond just emulation. It's a great example of how hardware can be used to create something truly unique and powerful – we'll continue to monitor its development closely.
