Multicore rendering

Do most modern games have this already implemented in it? Because when i bought tf2 recently, enabling multicore rendering gave me a nice fps boost, do other games do this too?

 

open task manager and take a look

 

You mean check cpu usage? My cpu usage isnt really that high whenever i game.

 

Yeah, but even if it's only 20%, you can still tell whether it's all being put on one core, or spread out over two or more.

 

Most games these days are multicore, especially any multiplatform title. Not too sure about the ratio of multicore games that are only coded to use up to 2 cores vs. those that use more than 2 if available, though, Crysis and GTAIV most certainly will use 4 cores, Crysis I think is coded to use up to 8 if there are that many available.

 

remember though that it also depends on how well the cpu load is distributed because for me on left 4 dead 2 if i leave the multicore rendering on it completely overloads the cpu keeping it at 100% usage resulting in unsteady framerates sometimes going as far as complete slowdown. this doesnt happen often but with a fast paced game like that it can mean the difference on making it out alive or dieing in front of the escape vehicle. the only way youll be able to tell is by having a program that can let you know core load in realtime like for example you can do this with everest and also rivatuner if you get a supported supplementary program

 

The slowdowns could be from thermal CPU throttling, if the CPU approaches it's max safe thermal upper limits, it will downclock to reduce heat dissipation, i noticed this in GTA 4 when my thermal paste wasn't making good contact with the heatsink (dryed out). It was getting to 96C.
