GPL: strange stutter; at wits end

2 posts by 1 person · 16 Oct 1998 - 17 Oct 1998

GPL stutters strangely after a few minutes of play. By the 3rd lap at the Ring, it's unplayable. The frame rate drops from 30'ish to 5 sporadically, and then returns to normal. The stutters start short with long times between, progressively growing to a continuous slow mo' jumpiness. The game time is slowed also to match when this happens; I managed to drive all of SchwendenKreuse in slow motion. (It's amazing how well I could hold the line given the extra time to jiggle the wheel; judging speed is hard, though.) The sound stutters, too, while this is happening, giving a strong feeling of acid flashback. Tonight, the replay was similarly affected, but this is the first time this happened. Previously, the replays happened in real time through the slo-mo jerky moments. I've done all I could from Alison's advice on her page. I defragged the disk, and set a fixed swap file size. Vcache is set to 12MB to match my machine's 48 MB. I've uninstalled and reinstalled the game; this only caused me to lose my setups. Turning off most textures sped up the frame rate nicely, but didn't change the bad behavior. Turning off skid-marks didn't help. The machine is a Compaq Presario 8772, P5 MMX, 200 mhz, 48 MB, onboard Interwave sound. Voodoo 1. Win95, DX 5.2. 3Com 3C900 ethernet. Generic joystick. No other software running; task scheduler disabled; no screen saver; power saver enabled but set to 45 minutes. Scanner software is loaded, but the scanner is powered off. I've done all I can think to do. The game ran fine when I first installed it some weeks ago (9/30). In fact, the power saver used to ruin perfectly good hot-laps after its 45 minute delay (none of this Shift-R stuff for me!). I don't recall it happening in other tracks; come to think of it, the problem started around the time I switched back to the 'Ring after running at Monza for a few days. I haven't run at the other tracks for any length of time... Ideas, anyone? The problem, I realize, is difficult to describe. I can video tape it and send an avi to anyone who might be able to help. The replays, of course, will run fine on your machine, and won't show the problem. Thanks. Michael.
Never mind. I just found out the brake or throttle pot is acting weird, or maybe stretched a wire tugging and pulling on the pedals at times. It's a 3 year old set of CH pedals. Tried recalibrating the controls and found out the throttle jumps values up beyond 300K. Really strange effect this has on the game, though... Looks like I buy a new wheel sooner than I expected. Michael.
