My Crysis tip - Cap the games frame rate for a smoother experience

post #1 of 3
Thread Starter 
Crysis is a game that every benchmarks, Is a game that everyone tries when they first install a new GPU and in this day and age we are now at the point were Crysis is playable on mid-range graphics cards.

I for instance can have a frame rate any were between 40-70fps with my 5850's playing the game maxed out with 4xMSAA.

The problem is the smoothness..... gunning around at 60fps+ only to turn a corner and see your frame rate dive down to the low 40's is extremely noticeable and distracting.

The only way to get rid of this is to buy a monster GPU set-up and run with V-sync enabled, Problem is that like me people don't have that kind of money to spend.

So the other alternative is to cap the games frame rate, Why you ask? Simple smile.gif

1. If your graphics cards only have to render to a set frame rate they will run cooler and consume less power as the graphics load will be reduced

2. Again, SMOOTHNESS..... from a game play point of view a game that runs at a constant 45fps is going to feel smoother then one that has a frame rate that spikes or drops here, there and every were.

3. Higher minimum frame rates, As the CPU only has to send a limited amount of draw calls to graphics driver to render it meens there's EXTRA CPU cycles left over for the game itself.

To cap the game to your desired frame rate enter these comannds into the games console or into a config file.

fixed_time_step = ( What ever the value is for your desired frame rate )

-0,0225 - > 45 fps
-0.024 - > 42 fps
-0.0255 - > 40 fps
-0.029 - > 35 fps
-0.0335 - > 30 fps

So as an example to cap the game at 30fps the command would be : fixed_time_step = -0.0335

Now as you can see these figures have a '-' ( Minus ) value at the start, if that minus isn't present it WILL NOT WORK...

This is extremely helpful with the later levels of the game which can have quite serve frame rates spikes and drops.

Go ahead and give it a try smile.gif

If you were going to drop into the mid 20s FPS when you turn that corner and suddenly see a dozen baddies, you still will with or without this cap. This is not a fix if you are having problems running Crysis- the reason your get such low framerates is because they are suddenly so many more polygons and textures and shadows to render on the screen.

Setting a capped maximum framerate lower than your maximum attainable framerates does nothing but keep your GPUs slightly cooler.

Wrong on so many levels.... my 5850's are always 90%+ loaded each without a cap, With the cap they can any were from 30% load to 70-80% load depending on location.

Less load = less heat and power...

And I never said it'll make your frame rates a million times higher...I said SMOOTHER......it'll make these drops less noticeable and less distracting..

Going from a fixed rate of say 35fps to 25fps is going to be less noticeable then going from say 50fps down to 25fps..

Instead of thinking you know best why don't you load the game up and actually TRY it...
