How to turn off mouse smoothing/acceleration

[summer87nights]

Apparently, this game uses mouse smoothing/acceleration...Not sure which one of the two but the mouse control certainly doesn't feel right...like in Bioshock... Anyone happen to know how to turn it off?

[Grimspoon]

I'm also curious about this.

The lag between mouse movement and what happens on screen is atrocious! Makes the game basically unplayable.

What really annoys me is when i jump into a vehicle and my mouse seems 4x sensative! can be really frustrating, even though all my mouse camera sensitivity settings are the same...im just thankfull for on the fly mouse sensitivity changes on my G9.

For the love of God if somebody knows a fix for this please let us know! I have basically stopped playing it until I can get the mouse problems fixed.

i have trouble when it comes to controlling turrets, my cursor shakes all over the plaece and is really hard to actually aim, the geurilla missions where your on the back of the blokes vehicle and have to cause a certain amount of damage to the EDF buildings are impossible for me atm

For all your laggy mouse problems with RFG - I've got a fix!

First, check for symptoms - use fraps and check fps. If fraps shows less than 40 frames per second or even worse - 30 - then there WILL be lags.
In many games 30fps is enough for playing comfort, but not in Guerrilla, because here we have high input lag, which is linearly dependent on overall framerate, but higher than input lag in most other games (like Crysis, which plays ok on 30fps), so to achieve smooth and responsive mouse look (without that "swimming" feel) you absolutely NEED higher than 50fps framerate!

So solution is rather simple - tune your video settings for good perfomance (50+ fps in most outdoor scenes), and your mouse look will be cool. There's NO mouse smoothing in the game or some other evil feature which prevents you from responsive controls - it's just high input lag, which won't be fixed with patch afaik, because console versions have it too (I've completed game on Xbox 360), and it would require heavy optimizations and maybe even not possible at all.

Same goes for your problem, manicmush - in turret shooting sections framerate falls even lower (easily 20-30, maybe worse on very weak systems), so input lags becomes just unbearable, while animations and effects remain quite smooth (remember - it's high input lag, which means much time between you moving mouse and hero looking in needed direction. The movement/looking animation itself in RFG may easily be smooth and not jerky).
So, turn down visual settings, lower resolution, disable AA and ambient occlusion - as long as RFG runs 50+ fps, there will be no noticeable lag. 60-80fps is better.

First you absolutely need to disable ambient occlusion (on my Radeon 5850 overclocked to 950MHz core and Phenom II X4 3.8GHz with 4gigs of DDR3 disabling this feature gives 30-50% framerate boost (from laggy 30-45fps to quite good 50-80 (everything on max, 1920x1080, 8x MSAA, 16x AF)). Then disable coronas (no impact on perfomance in my case, but who knows - plus coronas aren't very good here) and antialiasing. Next step is to disable soft shadows.
All these options will give excellent (easilty 100% combined on many slower systems) perfomance boost with minimum impact on visual quality.

If listed above won't help, then lower resolution (rule of thumb is to multiply new height and width and subtract result from old height*width and then divide by old height*width and multiply with 100%. Result will be how much perfomance in % you'll get for changing resolution in GPU-hungry game).

All the other options won't help perfomance much, but degrade visuals quite heavily.

Hope that helps - Red faction Guerrilla is very fun with easily the best destruction physics in videogames.

It's not a frame rate issue, it's a quality control issue. RFG is a sloppy port, and like most sloppy ports, this game has terrible mouse lag.

You should be able to disable mouse acceleration without gimping graphical detail.

Normal made-for-PC games don't have the issue while most 360-PC conversions do.

I've already said that it's not framerate issue - it is input lag! So while you can see comparatively high framerate (30-40fps) controls still lag maybe more than 80-100ms. With very high fps like 60 and more there's NO noticeable mouse lag in Guerrilla! Just try it.
It is not "sloppy port" because console versions (at least Xbox 360 one) are the same - controls lag (it's less irritating with gamepad, but still) and framerate can be anywhere between 20 and 30fps in quiet sections without everything blowing up. In PC version at least you can always customize settings to achieve magic 60+ plus mouse aiming makes everything much easier. And you don't have to pay for Demons of the badlands either.

Want console-level perfomance and quality on poor hardware? set 1280x720, everything on medium, turn off soft shadows, ambient occlusion, MSAA, anisotropic filtering and coronas - I bet you won't run into perfomance issues on anything dual-core with couple gigs of memory and 9600GT/8800GT (it'll be faster than xbox 360). Want better quality? Buy expensive PC, because perfomance isn't free.

There are MUCH worse PC games even among platform exclusives, so don't whine.
Just remember Saints Row 2 and imagine how bad could RFG PC be with its complex physics.

[Grimspoon]

DIONightmare, my computer is comparable to yours in terms of performance and you are correct, disabling the settings you pointed out, specifically AA and ambient occlusion did help bring the mouse lag into tolerable levels...

My issue is that if RFG had been made for PC and not ported to PC, gamers like us, gamers who purchase and play on relatively decent rigs wouldn't be disabling all the things we as a group appreciate; graphical detail and frame rate, in order to compensate for something as intolerable as input lag.

My opinion; do the port right or don't do it at all.

This worked, thanks

Yeah the vehicles are the worst.

They actually have negative acceleration on them. So the slower you move your mouse, the quicker it moves the camera, and if you want to move the camera fast, it's actually slower when you try to move the mouse quickly.

Total relic from console controller design.
