Virtua Racing not working properly on Gamecube

[Former user]

Original [issue 89](https://code.google.com/p/genplus-gx/issues/detail?id=89) created by luisx86 on 2010-05-25T01:44:37.000Z:

What steps will reproduce the problem? 1. Load Virtua Racing rom

What is the expected output? What do you see instead? After the SEGA logo it shows just a blank screen, if you return to menu and then back to game it shows some frames and then the image freezes.

What version of the emulator are you using? latest r452

Please provide any additional information below (video settings, console region,...) Using a NTSC Gamecube with default SVP cycles 850. In the genplus-gx 1.3.1 it works fine.

This is caused by frameskipping when 3D elements are rendered. This is very slow on the Gamecube because of the additional processor that need to be emulated (SVP chip) and the result is that frames are skipped (and not rendered !). I will try to fix the way frameskipping is working (I changed some stuff a while ago but since the Wii is running slightly faster than the Gamecube, I didn't noticed any issues) because it should not be that way.

For the time being, try lowering the SVP cycle input (650 should be fine), it will reduces the speed of the emulated SVP chip and emulator will skip less frame (but 3D elements 'framerate' will be slower)...
