Hi folks:
I decided to resurrect an old workstation to try out as a dedicated Zwift machine.
Although the PC (HP xw8600 workstation with a Xeon CPU, NVidia Quadro GPU, 12GB memory, SSD) feels very snappy running Windows 10, the results with Zwift are pitiful:
I’m wondering if this is because the Quadro GPU is not being recognised and used optimally by Zwift (OpenGL?), or whether it’s simply too old? Or both?
Follow up question: Would it be worth swapping out just the GPU for something known to run Zwift well, or is the PC simply not usable?
Thanks for any advice: it’s a long time since I delved into PC hardware!
yikes
CPU is really slow for Zwift as well, I’m afraid. The RAM is probably registered stuff, so can’t be harvested. Keep the SSD, stick it in a cheap Haswell base unit with 8GB RAM and a GTX 960. That’ll get you 60fps in 1440p resolution and Ultra detail in most solo rides, and 30-50fps in busy areas, group rides, with popular pace partners and most of Makuri Islands (25fps in all of Neokyo). Doable for under £200.
Thanks for the informative response. That’s the kind of calibration I was hoping for.
I’ll see what I can cobble together and at what cost.
(Normally I run Zwift on a 2015 MacBook Pro 15", which runs High profile/1440p @ 25 fps average. However, I don’t want to dedicate that machine for Zwift, so I have to swap it in and out.)
Just approved you. 
See the files section there, but bear in mind that Neokyo shits all over most of it.
