Hi everyone,
I’m only getting 30-50 FPS in Zwift, even though neither my CPU (i5-14400F) nor my graphics card (RTX 5060 Ti) are fully utilized. CPU load sits at around 30% during a ride (temperatures around 60°C, cooled by a Be Quiet Dark Rock Pro), and GPU load is at roughly 40% (temperatures also around 60°C). Vsync is enabled, and my monitor supports 144Hz and is G-Sync compatible. Vsync doesn’t seem to be the limiting factor either, as the FPS can definitely exceed 60 in less populated areas (e.g. high up on Alpe du Zwift or in Richmond).
Zwiftalizer 3.0 praises the overall system performance but also flags an issue, warning that there might be a CPU bottleneck (see screenshots). However, I really don’t see where that would be coming from.
Can you please help me out?
Best regards,
Clemens
Your average CPU load across all cores might be 30%, but what are the individual core utilisation figures? Chances are that the single core that Zwift uses is at 100%.
How does it perform when you are not in Makuri?
Somethings up, my i3 12th gen and 1060 gpu average 40-50 in Makuri at 4k and Ultra.
When I researched what PC to buy am sure the i5 12th gen and above was as good as anybody needed to Zwift and that GPU is a lot better than you need to Zwift.
This is the log from Alpe du Zwift yesterday. It is a bit better, but not much.
I am curious how busy the busiest CPU core is. I suspect you are CPU limited for some reason. That CPU has a lot of cores but Zwift won’t use them so it can look not very busy but is actually bottlenecked.
Something wrong there, I’m running the RTX5070 and the AMD Ryzen 9 7950X with 64Gb of DDR5 6000 and hit 120fps no problems at all in 4K-2160p. I would say the CPU is having trouble., my CPU is sitting at 3 to 5% utilisation, I have seen it hit 14% if it needs to.
GPU usage on mine is normally 30 to 40% which is what you want, ignore people that tell you you want 100%. You will hit into the 90’s when its needed.
I assume that’s average CPU utilisation across all cores. If so, that tells you nothing because it’s the utilisation of the single core that Zwift is running on that is important. The averaged figure is meaningless because you’re averaging in lots of idle cores.
Pretty much tells you everything you need to know aftyer testing, its just a number on the screen now when I ride.
You simply do some research and run free software like the benchmarking part of CPU-Z and Superposition Benchmark.
The 7950X is like only 15% behind the fastest production CPU on the planet for single thread and there is nothing in it for Multithread with an optimised 64Gb set-up
Bottom line is, based on a couple of months of running Zwift now I would not buy a 5060Ti to run at 120fps but it should be having no trouble at 100fps or 60fps in 4K-2160p.
All that said, the OP set-up is having unexpected problems, the performance should be better than that.
