I agree in most points with zingbat.
IMHO an even greater threat would be if it is possible to write games with C# with Managed DirectX that run on the XBOX 360. Does anyone know about Microsoft’s plans in doing so ?
I don’t know much about performance comapering java and c#, but I am very interested in where you got these info?
I only know about this comparison, which probably fall under the microbenchmark category and therefore may not be serious. Furthermore the statement from the website: “The Java server VM is faster than the client VM, which was new to me, because I don’t have that much Java experience” isn’t a good argument for relying on the results.
