Hi, I seem to get fairly low framerates in Zwift. Some days are better than others, but in particular, I participated in a group ride with a few dozen other riders on Sunday morning and the framerate was like that of a powerpoint slideshow for much of the ride. My system runs modern 3d games in higher resolutions and with higher graphics requirements fluidly. My specs are below:
Intel Xeon X5470 (Quad core 3.33Ghz currently at 3.75 Ghz)
Dual nVidia Geforce GTX 460 1GB video cards in SLI performance mode
Video Driver: Latest nVidia reference driver
Power management options disabled for cpu
Power management options disabled for gpu (all on performance mode)
System Memory: 8GB DDR2 PC-6400 @ 800Mhz
480GB SSD SATA3 HD, running at SATA2 due to motherboard. > 100GB free space
Internet: 5Mbps down / 0.5Mbps up
Operating System: Windows 10 Pro - clean install
I have a feeling Zwift might not be taking advantage of my SLI video card configuration? That being said, is a single nVidia GTX 460 1GB not enough to run Zwift optimally? The other games I run appear to be significantly much more graphic intensive and I run them at 1440P, whereas I run Zwift at 720P.
I output Zwift at 720P on to a projector which only supports that resolution, which is why I chose that. I have tried it on my main monitor at normal 1440P resolution and the performance appears to be no different.
