Re: [JAVA2D] BufferCapabilities and ImageCapabilities
Hi Andreas, what java version do you use? Which operating system? The 7900 should have hw acceleration enabled on Windows. Please run your app with this env. variable set and post the results: # set J2D_TRACE_LEVEL=4 # java YourApp Thanks, Dmitri [EMAIL PROTECTED] wrote: Hi everybody, I have been using Java for a few years now and want to get into Java game programming. Currently I am using standard Java 6 and want to do an FSEM game. However, when I look at the BufferCapabilities and ImageCapabilities before and after switching to 1024x768x32 FSEM I get the info that Image Caps. isAccelerated: false Image Caps. isTrueVolatile: false Buffer Caps. isPageFlipping: false Buffer Caps. Flip Contents: false Buffer Caps. Full-screen Required: false Buffer Caps. MultiBuffers: false which confuses me because I got a NVidia GeForce 7900 GS which has page flipping and lots of other stuff. Can someone comment on this? I would be very happy! Thanks a lot and best regards Andreas [Message sent by forum member 'meix' (meix)] http://forums.java.net/jive/thread.jspa?messageID=289421 === To unsubscribe, send email to [EMAIL PROTECTED] and include in the body of the message signoff JAVA2D-INTEREST.

Re: [JAVA2D] BufferCapabilities and ImageCapabilities
Hi Dmitri, thanks for your answer. My java version is jre1.6.0_07. I'm using Windows Vista Home Premium. The output after setting J2D_TRACE_LEVEL= 4 is [W] GetFlagValues: DDraw/D3D is disabled on Windows Vista [W] GetFlagValues: DDraw screen locking is disabled (W2K, XP+) [ I ] InitDirectX [V] CheckRegistry: Found Display Device 0: NVIDIA GeForce 7900 GS [ I ] InitDirectX [V] CheckRegistry: Found Display Device 0: NVIDIA GeForce 7900 GS Display mode set to: (1024,768,32) Image Caps. isAccelerated: false Image Caps. isTrueVolatile: false Buffer Caps. isPageFlipping: false Buffer Caps. Flip Contents: false Buffer Caps. Full-screen Required: false Buffer Caps. MultiBuffers: false [ I ] InitDirectX [V] CheckRegistry: Found Display Device 0: NVIDIA GeForce 7900 GS The first line of the output is very interesting. I will have to look into that. Do you have an clue how to enable DDraw/D3D? Why is it disabled??

Re: [JAVA2D] BufferCapabilities and ImageCapabilities
Hi again, I just solved it by setting the compatibility mode of java.exe to XP. Now I get [W] GetFlagValues: DDraw screen locking is disabled (W2K, XP+) [ I ] InitDirectX [V] CheckRegistry: Found Display Device 0: NVIDIA GeForce 7900 GS [ I ] CreateDevice: lpGUID=0x3acfa8 hMon=0x10001 [ I ] DDSetupDevice [ I ] DDraw::CreateDDPrimarySurface: back-buffers=0 [V] DDSetupDevice: successfully created primary surface [V] DDSetupDevice: successfully setup ddraw device Image Caps. isAccelerated: true Image Caps. isTrueVolatile: true Buffer Caps. isPageFlipping: true Buffer Caps. Flip Contents: Prior Buffer Caps. Full-screen Required: true Buffer Caps. MultiBuffers: true Current Display Mode: (1280,1024,32,60) [ I ] InitDirectX [V] CheckRegistry: Found Display Device 0: NVIDIA GeForce 7900 GS Display mode set to: (1024,768,32) etc.. (lots more) Looks good, but I'm wondering if there is a better way. In another forum I found that java 6 uses DirectX 7 (DirectDraw) which can collide with Vista's Desktop Window Manager.

Re: [JAVA2D] BufferCapabilities and ImageCapabilities
Yeah, releases prior to 6u10 have some real issues on Vista with the default pipeline, which is why it is disabled by default. I would advise against enabling it. Your best bet is to try the latest 6u10 build from jdk6.dev.java.net . Thanks, Dmitri [EMAIL PROTECTED] wrote: Hi again, I just solved it by setting the compatibility mode of java.exe to XP.
