I tested Atlasaurus on a gaming laptop (AMD Ryzen cpu, AMD 680m igpu and NVidia RTX 3080m dedicated gpu, 32gb ram), and sadly it crashes after i click "login". I deleted the appdata folders to see if it would fix it, but it doesn't. Also i tested on the igpu and on the nvidia gpu, same result. I noticed the webview (with destinations and so on) wouldn't show up on the login screen. it might be normal for a first login though ? (since i deleted all data). The previous Atlasaurus build was also crashing. I also excluded the executable and the appdata secondlife folders from the Windows AV. Side node 1 : Its work on an older gaming laptop with a Ryzen 4800H cpu, 16gb of ram, and nVidia GTX 1660ti. Side note 2 : The stream on that other laptop works (vs my post about it not working on the mac). Side note 3 : On that other laptop where the viewer works, i tested it on a popular crowdy dancing sim. It was working fine with the nvidia gpu, actually not maxing out the vram of the gpu. But with the integrated amd gpu, when it reached the ram limit (16gb) it crashed. This behavior isn't new for this machine though, when the ram is saturated in crowdy sims. The max allocated (v)ram on this machine for the igpu is 8gb. It was maxed out when it crashed. This might be the amd driver which detected a problem or the viewer detecting a problem with ram allocation. Of course i wouldn't normally use the igpu, but i thought it was an additional information worth being mentioned, since some people won't have a dedicated gpu. Some people actually have 8gb or ram, (or even 4gb) which won't let them enjoy crowdy places safely. For all those tests i was using the low-mid preset. Complementary information: In the same place, the Macbook Pro with 16gb of ram (unified memory) wasn't crashing, even though it was using more ram than the actual available ram. So certainly it's about how the amd driver deals with this situation .. or how the OS deals with it. I wrote 2 different reports in this post, related to 2 different platforms. If you wish me to separate them, you let me know :)
