I tried Zwift on my Acer Aspire R3700 last night and it was quite jerky (not the dried meat kind).

Is it possible to upgrade the graphics card on a small PC like this?

I’ve looked online but can only find instructions for upgrading bigger machines.

No, it’s a laptop style board in a tiny form factor box – there’s no PCIE slot for a GPU.

You can upgrade the ram, try running task manager when Zwift is running to see if it’s maxing out the RAM, if so it might help, but I doubt it will much, it’s a very modestly powered thing.

The issue with machines like that is theres just not any space and probably not an expansion slot, the graphics it uses is integrated into the processor.

You might be out of luck as those micro PCs just ar’nt designed foer the sort of use.

Thanks, I worried this might be the case.

Off to the shops for me then!
