ATI users - thelusiv - 07-25-2006 There aren't currently any VDrift developers using ATI graphics cards on our Linux development systems, and we're interested to know how well VDrift works/performs on ATI cards. Let me know if you are, and if you're interested in doing some testing....in fact, we haven't really heard much from ATI users (I know you're out there!) so, let us know of your experiences using VDrift with various ATI cards, on any operating system, if only to let us know how they perform. Thanks!

Both have 32 mb ati cards. It runs a little slow on my imac, only because its older but runs very smooth on my mini. - joevenzon - 07-26-2006 Yeah, I think you're right, 16 bits probably is enough. Maybe we should change this for everyone, as it might slightly bump performance... as long as we don't end up with z-fighting artifacts. My "24 bits is NOT enough" comment was left-over from a previous project that did need more z-buffer resolution. - thelusiv - 07-27-2006 Alex, if you'd like you can check in this change. - alex25 - 07-27-2006 thelusiv Wrote:Alex, if you'd like you can check in this change.i'll check this tomorrow on my desktop to make sure it doesn't break anything and then i'll commit it to svn. --alex-- - alex25 - 07-27-2006 alex25 Wrote:i'll check this tomorrow on my desktop to make sure it doesn't break anything and then i'll commit it to svn. i've checked in the code. i also checked in the code to catch fpe exceptions which is commented out, of course. if other brave souls want to play with it, remove the comment from the feenableexcept(FE_INVALID|FE_DIVBYZERO|FE_OVERFLOW); line, recompile and run under the debugger. hmm, this might work only under linux. i hope i didn't break anything for windows users with the #include <fenv.h> line. --alex-- - jeff - 07-27-2006 I have 2 computers both with ATI cards and the game works fine. Ill break it down a little PC 1 Windows (Gaming partition) P4 2.8G 512MB RAM (PC2700) AGP ATI 9200 w/128MB RAM Works very well but on some maps all the textures disappear and everything is white. I also get white flashes coming from under the car every now and then. I will plug in an old Geforce2 to see if these problems go away and post back. Yet to try on ubuntu will report back when i do PC 2 Windows Celeron 2.4G 512MB RAM (PC2700) PCI ATI 9200 w/ 128MB RAM Works just as well but again on some maps all the textures disappear and everything is white. post back if you want me to elaborate a little. - joevenzon - 07-27-2006 If you're worried about it on Windows, maybe add #ifndef _WIN32 and #endif declarations before and after that line. - thelusiv - 07-27-2006 jeff, the white textures problem is one that happens on all platforms with this version. Try exiting the game and restarting, then choosing the same map - it should be gone... Wait a little on installing on Ubuntu, and you can try the forthcoming Debian packages on it. Watch the front page for a new article. How well does the game perform on each of your computers? What resolution, texture size, and other settings do you use? |
