Hey everyone!
We have just pushed a Serious Sam 4 hotfix live. It's a relatively small update that takes care of some of the burning issues you have reported since yesterday's launch.
The update takes care of some nagging crashes related to older drivers and hardware, as well as various stability issues we have encountered. Overall, this update will make the game much more stable. It even helps out those on older Windows versions, which are still not supported but should be a bit more stable now.
Due to this being a hotfix, not a lot of other changes have been implemented, but I do have a short changelog for you.
The changelog is available on our forums, so feel free to type your feedback there as well: https://steamcommunity.com/app/257420/discussions/0/2840039920173473984/
Thanks for your support and patience. We'll start working on the next patch immediately.
Much love from Croteam!
Danny
