So I speedrun a game called Super Mario Bros. Crossover, an old flash game, and as I was doing some runs while in call with another runner we noticed I seemed to be able to get times noticeably better times on some stages than other players who do the same execution. For example in 1-1 I save a second over what anyone else is even capable of even if they do the same inputs at the same time, which is a lot of time to save in the first level of a 6-10 minute run depending on category.

Me and the player I was in VC with compared our CPU speeds to find that mine was noticeably faster, which might lead to this difference. Could CPU speed actually be the difference maker, and if so if there any way to re-time runs that takes into account different cpu speeds?

To make things a bit clear, I'm a mod for this game and even though its a small community, I take the competitive integrity of the leaderboard rather seriously. Because of this I'm not a fan of the idea of people losing multiple seconds over other runners simply because of their CPU speed, especially when I'm one of the people who gains the advantage.

I've heard of games speeding up/slowing down depending on your CPU speed, so it's definetely a possibility. I'm unsure what to do in these sorts of cases, but maybe finding some sort of third party program that caps the FPS at 30/60 could help with leveling the disparity between PCs.

Does anyone here know of such programs? I'm gonna look for some on my own but if anyone knows a good one let me know.

The only one that comes to mind is Dxtory, which the PC folks at Spider-Man 2000 use to cap all runs at 30 FPS, but if you look around google you're bound to find a few more.

If you need help as to how to use it to limit FPS, this short video guide seems enough to get it working. That being said, apparently this one only works with DirectX games, so it's most likely not going to work with a flash game, but give it a go and see if it does the trick for you guys. Hope it helps!

So update, tried messing around with RivaTuner. The result was what I was looking for, but taken a bit too far. I went from seemingly have a large time advantage (roughly 1-1.5 seconds in 1-1 alone) to a large time disadvantage of an equal amount as the advantage. Tired now so done with my testing, will try more stuff tomorrow. Any other suggestions are welcomed!

Glad to see you're getting some semblance of results at the very least! Hope you eventually find the perfect solution

My only run had a bad pc speed so it would be useful if they could fix these problems so it could be fair.
