@nadenislamarre in fact, the only game that doesn’t work on xu4 is outrun 2006, but it works on x86-64. I dont know why. It seems that reicast (frameskip), ps1 (frameskip), n64 (bad sound) is lagging a bit. i will retry with a new build. on x86-64, ps2, dolphin is working well with mobile nvidia 1050, no more lags. Thanks
