Hi folks,<br><br>My Nvidia 6200 AGP died the other day, so I picked up an 8400GS PCI, <br>thinking great I will be ready for the VDPAU and it should just be a pop <br>it in and everything will work nicely.<br><br>This certainly hasn't been the case, the 6200 was able to playback 1080i <br>video perfectly with xv on my LCD panel with a DVI-HDMI connection. <br>During the instance the CPU would be around 75-80% with 60-65% coming <br>from mythfrontend, the rest coming from X or other process. <br>After replacing it with the 8400GS, I get loads of tearing and just a <br>horrible looking picture, even with SD (though SD is watchable sort <br>of). The problem seems to be with X windows taking more CPU time then <br>mythfrontend, playing 1080i about 55% is going to X and 40% or so to <br>mythfrontend.<br><br>I've researched it as much as I could and tried all combinations of <br>UseEvents, Sync to Vblank, OpenGL sync all to no avail. <br><br>Thanks,<br>Lee<br><br>Kernel: 2.6.26-gentoo-r3<br>Processor: AMD Athlon 64 3000+<br>MotherBoard: MSI Neo2 (nforce 3 ultra)<br>Memory: 1GB<br>VideoCard: PNY GeForce 8400GS PCI 512MB (Nvidia 8 series)<br>Video Tuners: Fusion HDTV USB, PVR150, HDHomeRun<br><br>xorg-server-1.3.0.0-r6<br>nvidia-drivers-177.80 (also tried 177.82 and 180.11 same problem)<br>mythtv-0.21_p16505<br><br>xorg.conf (worked with my old card)<br><br>Section "Device"<br> Identifier "Device0"<br> Driver "nvidia"<br> VendorName "NVIDIA Corporation"<br> Option "RenderAccel" "True"<br> Option "UseEvents" "True"<br>EndSection<br><br>Xorg.0.log<br><br>(**) NVIDIA(0): Option "RenderAccel" "True"<br>dme(**) NVIDIA(0): Option "UseEvents" "True"<br>(**) NVIDIA(0): Enabling RENDER acceleration<br>(**) NVIDIA(0): Use of AGP disabled per request<br>(II) NVIDIA(0): NVIDIA GPU GeForce 8400 GS (G98) at PCI:3:0:0 (GPU-0)<br>(--) NVIDIA(0): Memory: 524288 kBytes<br>(--) NVIDIA(0): VideoBIOS: 62.98.20.00.51<br>(II) NVIDIA(0): Detected PCI Express Link width: 1X<br>(--) NVIDIA(0): Interlaced video modes are supported on this GPU<br>(--) NVIDIA(0): Connected display device(s) on GeForce 8400 GS at PCI:3:0:0:<br>(--) NVIDIA(0): TSB-TV (DFP-0)<br>(--) NVIDIA(0): TSB-TV (DFP-0): 330.0 MHz maximum pixel clock<br>(--) NVIDIA(0): TSB-TV (DFP-0): Internal Dual Link TMDS<br>(II) NVIDIA(0): Assigned Display Device: DFP-0<br>(II) NVIDIA(0): Initialized GPU GART.<br>(II) Loading extension NV-GLX<br>(II) NVIDIA(0): NVIDIA 3D Acceleration Architecture Initialized<br>(II) NVIDIA(0): Using the NVIDIA 2D acceleration architecture<br>(==) NVIDIA(0): Backing store disabled<br>(==) NVIDIA(0): Silken mouse enabled<br><br><br><br><br><br /><hr />Send e-mail faster without improving your typing skills. <a href='http://windowslive.com/Explore/hotmail?ocid=TXT_TAGLM_WL_hotmail_acq_speed_122008' target='_new'>Get your HotmailŪ account.</a></body>
