Re: Crap: GP3 && MSFF using all CPU (and beyond)

Microsoft force-feedback wheel overloads CPU in GP3

A user found that enabling force feedback with a Microsoft wheel pushed GP3's processor occupancy to 250 to 300 percent. Posters noted the Microsoft wheel was known to use far more CPU than the Logitech wheel, and a fix was found by installing DirectX 7a, though this exposed GP3's left-pulling force-feedback problem.

Yes, I had exactly the same problem when I bought GP3 yesterday. The solution is to install DirectX7a (note the 'a'). You can download this at Microsoft's web site. I was previously running DirectX7. The little 'a' fixed the problem wonderfully. Processor occupancy is now the same with or without FF. I also get the problem of the wheel pulling to the left all the time, but I have just seen a solution to that (untick the "map X to Z forces" [not sure if letters are correct] in the game controller control panel applet). I'll try that when I get home later.

Hi, As subj. says.....enabling FF in GP3, and the OCC climbes to 250%-300% !!!!!!!!!! Anyone else? Solution? Specs: MSFF attached to SB-Live P2-400 w. TNT-1 Runs about 90% OCC with no FF........! No probs. in OF1R or other games....

Hello, Well, that disc. can go on forever.....Since the Wheel works perfectly with all my other Sims. I know from other threads, that this OCC problem isnt for all with MSFF. Is it the game? Or the wheel? I dont know... All I know is that I've paid big $ for a new game-....I had to yank out my V2 card, invest quickly in a TNT just to get satisfied framerates....And of course this FF problem which means that I dont even bother to start up the game.....Its dissapointing that the software makers is using me as a beta-tester!!! Crap. I think i'll have another round of solitaire... -TH Simon Brown <[email hidden]> skrev i en nyhedsmeddelelse:xDpg5.1590$[email hidden]... > It must be that wheel, FF has no speed impact with my Logitech.

Vintook 29 Jul 2000 13:28 UTC#248462
When GPL was patched to include force-feedback all the available wheels were tested by someone and it was found that the MSFF used the most CPU cycles where as the LWFF used the least. All other wheels were in between but closer to the LWFF side. The MSFF was a the CPU hog of the bunch. Now that the processors have gotten faster over the last year, most people probably don't see the hit as easily.

OCC from 80% up to 250% because of the cpu cycles? Not realistic. Besides....I can play OF1R, NFS, etc without problems. > You didn't read any of the reports here before you bought?

Yes I did.....didnt think it was unplayable though.....opinions differ, that goes for all gameplay.....but theres a long way from messy gameplay to actual errors in implementation. -TH

Rob 30 Jul 2000#248130
You must have also followed my advice about unticking the axis force mapping box. When I got home and tried this it didn't work (I lost all FF like you), so it looks like there is no current solution to the pulling left issue. So, to recap: Make sure DirectX7a is installed. Make sure the "map X to Y forces" box is ticked. Live with the left pull (for now) Rob [Sorry if this message gets through twice - bit of a problem with dejanews] In article <93Ig5.7235$[email hidden]>, "TH" <[email hidden]> wrote:

Hi, Well...I checked the threads about FF not working and did the "axis-thing" like you suggested. It didnt work. But this morning it works?!!!!!! Now the really strange part: Now I really understand why people are screaming about the "left-pull" of GP3's FF.....With DirectX 7, there was NO left pull.....Forces worked as they should....Banks and curves when right through the Wheel as it should.... Nut now with DirectX 7a I have the mentioned left-pull, AND curves doesnt work either....So it looks like a DirectX / GP3 error? If I'm right it should be fairly easy to make a patch....lets hope.. Anyways, thx Rob -TH <[email hidden]> skrev i en nyhedsmeddelelse:8m0juu$j3r$[email hidden]...

Just a though here, I may be way off the mark, but could it be that GP3 is modelling the torque of the engine when you say it pulls to one side? Or does the pulling to one side occur all the time? You know what I mean, the way the engine tries to twist when it is revved hard, and the car veers to one side when you floor the throttle? I don't have FF so am only guessing.... 8-) *Peter* - http://www.cix.co.uk/~peterpc/home.html
