Render.perfoverlayvisible 1 Bf3 Performance Monitor

[tater2sacks]

BF3 has an amazing performance monitor you can check if the CPU or the GPU is the one bottlenecking:render.perfoverlayvisible 1

Open console and type "render.perfoverlayvisible 1" o to turn off.

Use this to know what part of pc is working most to play game.

Basically the graph shows render rate in ms (milliseconds).

 

The higher the MS render rate the worse that particular component is doing (CPU or GPU).

 

You want the lowest figures and you want the graph to be lower than higher (reversed).

 

So if your CPU is BELOW your GPU then your GPU is the problem/bottleneck etc.

GREEN (GPU) BELOW YELLOW (CPU) = CPU is slower

 

So if your GPU is BELOW your CPU then your CPU is the problem/bottleneck etc.

YELLOW (CPU) BELOW GREEN (GPU) = GPU is slower

The Higher the graph the worse your performance, the bottom Bar on the graph is 60fps while the middle bar is 30 fps, top bar being 0 fps.

 

Spikes in the graph indicate an unstable system/performance but hard to know what causes this?

 

Here is some more pics so people understand how it works:

 

GREEN = GPU, YELLOW = CPU.

Summary:

You want the graph to be stable as the pic above shows (no spikes) and you would ideally want both CPU and GPU to be at the same level (60fps if possible).

 

Here you can see why disabling HT is so important. Remember: The numbers in the graphs are milliseconds and not FPS so the lower the better.

 

Here with HT enable. Take a look at the spikes. Basically those spikes are when you stutter or game lags/freezes also you can see a much lower rate (milliseconds) than with HT enabled. This is a no brainer for me. HT disabled is the way to go.

I know that . Takes up too much space on my monitor so I don't use it.
