Hey all. So the team is aware of this issue with the swing meter moving erratically for players on Windows using older/low spec hardware. I was working with Support, asking players that messaged in what hardware they were running, and seems to be affecting players that are using CPUs that have an initial release date of 10+ years ago and no dedicated GPU. Tried it on an older system of mine with an i7 from 5 generations ago (9700k) and a GTX 1080 and had no issues, even disconnecting my GPU and running on board graphics the game ran fine, but these older systems from 2008-2012 that players reported having issues on were experiencing this swing meter stutter.
If you are running newer hardware and are still seeing this swing meter issue, let me know and I can bring this up with the team. You can find your PC and CPU info by selecting the Windows Button, Settings, System, and then About. If you do a Google Search for your CPU model and "release date" this will give you when that CPU was released. For example, one player wrote in they were using an i3-370m, which was released in 2010.
Info was passed along to Q/A and they are looking into it. They are also aware of the issue with Callaway balls not rendering color correctly and avatar opacity not looking right (showing a dot/grid pattern when the avatar is translucent). Ball color and avatar opacity I would estimate being fixed in the next couple updates, but no news on the swing meter for these older systems.
