Evolve PC: Remove 60 FPS Lock, Fix Mouse Acceleration & Smoothing

Evolve's closed beta didn't ship this weekend without its share of regular PC annoyances. Among many others, the most immediately noticeable restrictions on Evolve's PC closed beta are its locked framerate (FPS) and awkward mouse lagging / acceleration -- here's how to fix these problems.

Note: Our Evolve beta GPU benchmark is already online here.

Unlimited FPS in Evolve for PC 

Evolve runs on CryEngine, so removing the 60 FPS limit isn't too difficult. To remove the framerate cap on Evolve, perform the following steps: 

• Navigate to \Program Files (x86)\Steam\SteamApps\Common\EvolveBeta.
• Locate “system.cfg”
• Beneath the other “sys_” entries, ADD the line “sys_MaxFps = 500”

This will cap your FPS at 500. You could also set it to your monitor's refresh rate, e.g. 120 or 144.

Next, ensure V-Sync is disabled in the game settings.

Note that changing this setting will increase background video (like those found in the menu system) playback speed.

Mouse Lag & Acceleration in Evolve

Unfortunately, there's not presently a silver bullet to cure all mouse lag and smoothing / acceleration problems in Evolve. We've discovered a few different solutions depending on the root cause of the problem, but the mouse is loosely tied to FPS, so hardware that struggles to stay above 60FPS may exhibit additional input latency.

Among the first things to try, nVidia users can perform the following change:

• Navigate to your nVidia control panel.
• Select “Manage 3D Settings.”
• Locate “Program Settings,” then change the program to Evolve in the drop-down.
• Locate “Maximum pre-rendered frames” and change it to 1. 

This will ensure only a single frame is kept in the framebuffer at any given time, which will reduce general choppiness and aid in input response.

AMD has similar options.

If this does not resolve the issue, attempt making the following system.cfg change (see above):

• Navigate to the same folder as above.
• Locate “system.cfg”
• Add these items to the configuration file:
• i_mouse_smooth = 0
• i_mouse_accel = 0

This doesn't always remedy the issue, but it's worth trying.

Beyond this, ensuring that v-sync is disabled and modifying graphics settings would be the next best bet.
