CRIT skcraft runs only on integrated graphics (does not use gpu)

[Envel-Nikita-Gutsenkov]

I haven't been able to figure out why skcraft doesn't use, say, rtx, but uses integrated intel graphics. There is no such problem in the official launcher. An unmodified version from the skcraft source code has been tested. Tested on various hardware.

Do you mean the launcher itself, or the game?

In #86 it seems the solution is running the game with javaw; my guess is that this initializes the graphics context earlier and the GPU switching software picks up on it. I can put in a patch to try this. But it's probably difficult to do much else; switchable graphics isn't a standard and doesn't have any standardized APIs, to my knowledge.

I mean the game. Unfortunately, the problem is not in the java/javaw choice (I also tried java flags), and the code that is proposed in #86 is no longer available, so I can’t try it. The problem is observed only in skcraft :(
I tested on different hardware and in no case did it run on the GPU

I imagine the diff was changing the following line in JavaProcessBuilder to invoke javaw instead:

Launcher/launcher/src/main/java/com/skcraft/launcher/launch/JavaProcessBuilder.java

Line 91 in 6003069

File javaBinary = new File(getJavaBinPath(), "java");

But yeah I can't confirm this is a solution. Can you also provide the following details for each affected system:

• Operating system
• Model of the Integrated GPU
• Model of the Dedicated GPU

I have a laptop with switchable graphics myself (Linux, intel + nvidia) so I'll be able to do some Linux-specific debugging at least.

It was all so simple, but I didn’t realize it :D Thank you very much!
The problem is solved by replacing it with File javaBinary = new File(getJavaBinPath(), "javaw");

Although I think this should be fixed in this skcraft repository?

[hedgehog1029]

Yeah I'll apply this change here.
