Does Hardware-accelerated GPU Scheduling boost performance - Tested with RTX

Conclusion - Is Hardware-accelerated GPU Scheduling worth it?

While Hardware-accelerated GPU scheduling sounds like a great feature, it must be remembered that most PC games don't have a problem with memory utilisation, at least right now.   

Another thing that's worth noting is that Nvidia has stated that Hardware-accelerated GPU scheduling "can potentially improve performance and reduce latency", which means that performance boosts which come from this technology were always going to be marginal at best. If the feature offered us more than that, you could expect Nvidia to be singing about it from their rooftops and publishing their own benchmarks on the matter. They aren't and that says a lot about how useful this feature is right now. 

Moving forward, games are going to start putting more stress on memory controllers. Both the Xbox Series X and PlayStation 5 are upgrading to 16GB GDDR6 memory configurations and higher resolution targets, which means that future PC games will target more memory and demand more bandwidth than ever before. 

Perhaps we would have seen a larger performance impact on more bandwidth-constrained Nvidia graphics cards, like Nvidia's GDDR5-based GTX 1650 and GTX 1660 (non-Super). Unfortunately, we have neither of these GPUs in-house to test at this time. 

Ray-tracing is also going to become a lot more common over the next few years, and so far, ray-tracing has been found to be very memory intensive, both when it comes to VRAM capacity utilisation and bandwidth requirements, which could make Hardware-accelerated GPU scheduling a lot more important in the future. 

Right now, PC gamers shouldn't expect Hardware-accelerated GPU scheduling to deliver huge performance enhancements. If there are any performance gains, they will be marginal at best. While that isn't something to get excited about, bringing more hardware acceleration to the GPU ecosystem is undoubtedly a good thing. 

So far, Nvidia is the only GPU manufacturer to support Hardware-accelerated GPU scheduling on their latest graphics cards. AMD may follow Nvidia's lead in time, but at the time of writing team Radeon has been silent on the issue. That said, given the minimal, arguably non-existent performance impact of this update, does AMD really need to rush its support for it?

Maybe more of an effect can be provoked when simulating a laptop-like environment, by e.g. restricting the GPU to 8 PCIe-lanes and compare the performance theretoQuote

That's an interesting hypothesis. Definitely something that's worth investigating.Quote

No input lag tested? It would be nice to see if input lag improved under 100% gpu utilization or some situation like that.Quote

For anyone looking into a slightly more in depth explanation of exactly what this does MS wrote a blog.
https://devblogs.microsoft.com/direc...pu-scheduling/

While we may not see many performance differences now we can in the future as drivers get better at handling the new offloading work from the CPU. Early drivers after all and they are still going through validation and testing on MS's end. Nvidia and AMD may have the support but doesn't necessarily mean it'll do anything.Quote
