RE: [Xmame] Newbie: Compiling Nvidia Support

[Samuel, Brett]

Thanks for clearing up the DGA issue. The reason I tried the xgl target was because I was hoping that performance would be better than windowed x11.   I am using a GeForce2 on a Pentium III 550 with 256MB RAM. My hardware is definitely a bottleneck, this is more apparent on newer games.   However, my performance under the dreaded win32 is much faster on exactly the same hardware. I have been given quite a but of good advice, what I intent to do this evening is:   Compile my own kernel to optimise performance. disable all the goodies like glaa and cabview. try the SVGA target ( battled getting it working last time, but didn’t try too hard either)     Thanks again for all your help.   Brett Samuel Unix Pre-Sales Specialist Enterprise Storage Group Compaq Computer (PTY)Ltd Telephone: +27 (0)11 775 5339 Direct Line: +27 (0)11 775 5401 Facsimile: +27 (0)11 775 5339 Mobile: +27 (0)82 783 8521 -----Original Message----- From: Samuel Davidoff [mailto:[EMAIL PROTECTED]] Sent: 19 February 2002 03:54 PM To: [EMAIL PROTECTED] Subject: Re: [Xmame] Newbie: Compiling Nvidia Support   just to be clear on a few things-   dga and specialized modelines are only necessary for the x11 target. OpenGL uses its own (non-DGA) method to get fullscreen, and does scaling at the graphics card level so modelines aren't necessary.   not that any of that should impact your performance.   as to that issue - what are your other specs? i'm a pretty big xmame.xgl user and get good framerates and speed on an Athlong 800 w/ 128 meg of ram. I've also had ok speed on a PIII 733.   I think CPU speed is a lot more crucuial than graphics card for mame. I only have a TNT2 and, as I said, get good framerates.   one easy test is to compile the x11 target. see how it runs in a windowed screen (i.e. without scaling). what kind of framerates do you get there? ----- Original Message ----- From: Samuel, Brett To: [EMAIL PROTECTED] Sent: Tuesday, February 19, 2002 8:40 AM Subject: [Xmame] Newbie: Compiling Nvidia Support   Hi,   I’m just another idiot on a crusade to build their own arcade cabinet. I would like to use Linux as the operating system for obvious reasons, which brings me to Xmame. I have attempted to compile X Mame to use OpenGL on X11 still find the performance sluggish when compared to Dos or Win32 on the same hardware.   Am I doing anything stupid which is making X mame use software OpenGL rather than Hardware?   Here is what I did:   1. install redhat linux 7.2 2. download and install Nvidia’s X server for my GeForce 2 MX 3. Run Chromium BSU ( confirm that openGL hardware is working 4. Download xmame .58.2 source and untar. 5. copy makefile.Unix Makefile 6. make the following edits to the make file: disable DISPLAY=X11 enable DISPLAY=xgl change IL = ‘-DINLINE-static inline” to read IL = -DINLINE-static add –DGLU_VERSION_1_2 to the GLCFLAGS enable DGA=1 make 7. make install 8. add modeline to my XFree86-4.conf files for 320x200 9. exec xmame.xgl –fullscreen rome_name Was there anything that I did wrong? Is there anyway I can improve performance?   Regards, Brett Samuel Unix Pre-Sales Specialist Enterprise Storage Group Compaq Computer (PTY)Ltd Telephone: +27 (0)11 775 5339 Direct Line: +27 (0)11 775 5401 Facsimile: +27 (0)11 775 5339 Mobile: +27 (0)82 783 8521
