FPS Issue

Discussion in 'Formula SimRacing' started by Nick Rowland, Jun 9, 2010.

  1. Hi guys,

    I've recently formatted my PC and after re-installing rFactor and copying all the old user files across I've had constant FPS issues.

    Even with a fresh rF install and a new PLR I still have FPS issue. I have the exact same settings I had prior to formatting and yet my FPS is stable but then will just glitch down to 30. I've tried all different tracks and mods and it's the same on every single one.

    I've tried different drivers also and configured different things in graphics properties. Still the same problem...

    This doesn't happen on any other game either. iRacing, Bad Company 2 and Modern Warfare are all fine.

    I've got a Radeon HD4580 Graphics Card. And I know this works cause it worked prior to format.

    Anyone got any ideas on what it may be?


  2. I don't know that much in that dept, but check in your Catalyst Center, in 3d options, that you have everything set to "let application choose" or something (don't know what it is in english, basically deactivate all the AA and AF).
    Then put them as you want in the game. Maybe that helps?
  3. That has actually helped a bit. But I think I found the problem. Looks like when I formatted my PC I installed an old set of Motherboard drivers. I've just found the updated ones released last year. Dropped them on and it seems to be running a bit better now. If anything quicker and a bit cooler also.

    But that graphics thing you've mentioned I will also make sure on that. Cheers.

    Try to delete the d3d9.dll in your rfactor installation, if this file is available.
  5. My FPS issue has come back.

    I installed all new Motherboard drivers and seemed to be ok but it's back again. My FPS is never stable. Some parts of the track it's over 200 then other parts it's 90. It constantly fluctuates but it's causing jumping and it's getting hard to drive it.

    Like I said previously it worked fine prior to format.

    Any ideas welcome


  6. in case you have a dualcore, maybe check if the fullproc command is set

    What exactly does the +fullproc command do? I assume it has something to do with multi-core processors.

    I've had problems with several old games (not rFactor) that don't like running on multiple cores, and I've had to go through a complex process to rig the .exe to only use one core. Is this what the +fullproc command does?
  9. it makes the game use both (or all 4) cores, this gives a little fps increase (for me this was about 40-50% more fps). But it can make rF run unstable, so test it before you use it in a race.

    It doesn´t use the full advantages of a multicore CPU though, but always worth a try.
  10. I don't have a shortcut I just run it directly form the folder...
  11. Then ctrl+alt+supr when running the game. go to processes section and right clic on rFactor.exe -> set afinity (or similar, don't know how it's in english, sorry) and select all cores, apply, and keep driving ;)
  12. or just drive all the time with the fsr manager, there is the option to activate that thru the manager :p but is the least pratical of all the options already said here :D
  13. If u put this on the target of the shortcut works as well.

    "D:\FSR 2010\rFactor.exe" +fullproc
