Is FIFA 2005 internally locked to 30 FPS on pc port? No matter what the FPS counter shows, the game is just running at 30 fps and just duplicating rest of the frames, so it can show 500+ fps but the game is actually running at 30 fps. The ps2/xbox/gamecube versions all ran at smooth 60 FPS.
FIFA 2004 is a stuttery mess on newer hardware too. That game seems to be not locked to 30 FPS internally but stutters like crazy regardless of your frametimes.
Would be nice if these mods can be converted to work on consoles versions [especially xbox version which has the best visuals]. Looking at the file structure, it seems like pc and console ports are fairly similar and most of the tools straight up work with importing and exporting the files. I've managed to even get the LOD modifications to work on xbox. However, on console ports the texture format is .xsh instead of .fsh and thus none of the texture modifications work on xbox. And so far I have not find any tool to extract and import images into .xsh format.
