Graphics Cards For Planet Explorers
Update: Here's the full list of cards that support openCL as of March, 2012. http://www.phaseone.com/Search/Article.aspx?articleid=1720&LanguageID=1
We've been getting a lot of questions regarding Planet Explorers where the player will be standing in midair with vegetation and the water plane rendering beneath. This is due to the graphics cards not being able to render with opencl (this might also cause crashes upon finished loading). Our voxel terrain system needs opencl to correctly convert voxel terrain to renderable polygon.
If you want to check if your GPU is opencl compatible, please go here and download GPU-Z. This software will display at the bottom when opened whether your card has opencl.
So far, we're pretty sure that on the ATI side, HD 5000 series or above supports opencl 1.0 (which is all Planet Explorers needs). On the Nvidia side, GeForce 8600M or above and GT100 series or above support opencl. If you have these cards but still have problems, update your graphics driver. Nvidia cards before the these series might also support opencl, but we're not sure which. For ATI though, any card below HD 5000 series at this moment does not support opencl. ATI HD 4000 series is a weird one, supposedly it supports opencl 1.0, but when we run the latest driver version 12.7 through GPU-Z, we detect opencl only through CPU not GPU. So we're putting that one down as unsupported for now and hope that AMD will support it with a driver update in the future.
As far s we know, all integrated gpu except for the AMD Radeon 6000M, 7000M series and Intel HD 4000 series do not currently support opencl.
Hopefully that's helpful. Before anyone start asking us to lower the specs, newer tech (and a giant infinite voxel terrain system is pretty new) requires newer hardware, so it can't be helped.
