I find the advice here questionable.

-The two settings in steps 5 and 6 don't actually do anything and they are clearly marked as "not ready to use" in the dsfix config. These steps should just be removed.

-Unless a user has 120Hz monitors but keeps their desktop at 60Hz (why would anyone do that?), there is no reason to use fullscreen mode at all.

-Not all "high frame rate" monitors are 120Hz. For the sake of accuracy, the instructions should read, "Change FPSlimit 60 to the refresh rate of your monitor, for example FPSlimit 120".

-It should also be noted that the physics engine is reported to have issues at 60FPS- a reasonable assumption is that the issues would multiply with the increased FPS. I use 60FPS and I have only experienced one instance of falling through the floor in many hours of play, but there should still be a warning that this could happen.

I'm creating this discussion because I feel I should explain some of these corrections before just jumping in. I'll make the changes myself if there are no objections in a few days time.

As far as I know too, steps 5 & 6 does nothing. But 120Hz is regarded as HFR here among other places. Thus why it's 120fps on every page.

Problems with the physics-engine at 96Hz has the same effect as an unlock at 60fps; barely noticeable unless you're actively looking for them. Dropping down a ladder once and clipping through the world can happen once, but not again after coming back after respawning. I don't think the higher frame-rate you have the more problems you get.

Definitively.

Though, I would recommend you to check whether there are actually problems with high framerates before everything else..
My hint would be to lower as much as possible details (so you get as much frames per second as possible) and play a bit to see if something gets screwed.

In this case the entire fixbox would become pointless

Well, we can already confirm problems going over the 30fps lock.

Unless we're checking if there are more problems at a very high frame-rate.

I realize 120Hz is the most common, I was just proposing a more idiot-proof set of instructions. It's not terribly important.

If the bugs are twice as frequent at 120FPS vs 60FPS, that's still an insignificant number of bug encounters: at 60FPS I have encountered one instance of falling through the floor in over 100 hours of play. Double that is once every 50 hours under 120FPS, so I don't think it will be easy to confirm this. In that light, I suppose it doesn't need to be mentioned under HFR as it is already mentioned under essential improvements, where a 59FPS cap is recommended. But again, for the sake of clarity/idiot proofing, it might be a good idea to make a note of the clipping issues under HFR.

I think we're all agreed about removing steps 5-6, I'll do that for now.

I've made an official note of "falling through the floor for ladders" since it wasn't previously mentioned and it kind of important to know. I've also confirmed that increasing the framerate beyond 60fps causes additional issues, referenced with video evidence I personally captured. I've got it on my onedrive, is there a way to upload it to the wiki itself?

Tmplt (talkcontribs)

I don't believe there is a convenient way to do that here. It's probably a better idea to upload it as an unlisted video to Youtube and link to it instead.

Mirh (talkcontribs)

Elaborate better.

Is there just a limited amount of bugs that only gets triggered 1/0 (yes or no) when you pass a specific threshold?

Or is it that the more you depart from the normal cap, the more bugs become important and noticeable?
For example, would it be possible to play at, say, 600 FPS ?

Link Satonaka (talkcontribs)

Falling through the floor at higher than 30FPS is an old and well known issue, search for "ladder" in the comments here http://blog.metaclassofnil.com/?p=232

I can't elaborate much, the issue is probably just "collision detection" which fails in different ways at different framerates. I do not encounter the ladder issue enough to properly give you the highest "bug free" framerate; somewhere above 30 is all that is certain. I could find out exactly when the slow-running bug manifests. The problem is I know it manifests around 80FPS, and when you're that close to 60fPS you might as well just use 60FPS...

Re: Limited amount of bugs- up to 120FPS there are for sure two known bugs. I don't know if more will manifest at 600FPS.

If there's something that GTA:SA as taught me is: you'll be less annoyed overall with constant 30fps cap than with many little not-so-consciously-noticed bugs.
You can always get used to the first problem, instead with the other you never know if what you just did, do and are going to is really what you was exactly supposed to do, or just a physics jest

My vote goes for HFR = false.
