MAking UDK GAME render form CPU and not GPU-solved

[Racer X]

Hi there,
I´ve got this thing bugging me, it´s probably a stupid question, but need to ask it anyway: a UDK made game renders mainly from the GPU card, but on a laptop, Is there anyway to make it render form the CPU as the primary processing force?
As a prospect developer, you can´t expect the general consumer having to buy a highend graphics card just to play your game (since Epic advertises that UDK can be used to make any game type, so I´m gearing toward a simple games, not FPShooters, or fast paced ones).
Thanks

How are you deducing it is using more GPU than CPU? We have been told for years that Unreal Engine 3 is more CPU dependent than it is GPU. If that has changed then I'm not exactly sure when.

A game will most likely not be any faster when it's rendered through the CPU instead of the GPU, since the GPU is designed to render things, where the CPU is more for general computing.
Also, the type of game has no effect whatsoever on what kind of graphical horsepower you need.

Well, when using the command line Stat Unit, it show the GPU on it´s knees...143 ms colored red blood

by the way henrik, I liked your music, (heavy stuff- i´m also into music mor hard rock oriented)and learned how to use flash from your tutorials. Thanks

The term that you are looking for is "software render".

Unexpected but nice to hear!

Yea, and a CPU would do that even slower.

The simple fact is that low-end laptops are not designed to run AAA games, and there's no magic software switch to make it so. Even the most basic GPU is far more efficient at rendering than the fastest multicore CPUs.

Ok people I get the picture, I got carried away with the "any type of game" from epic´s pitch sale, I guess they forgot to squeeze "AAA" in that sentence thanks for the input.

Well, tbh if it runs fine on an iPad then you must be testing it on quite a poor laptop.

You have to engineer your game for the target platform. iOS games have to be very careful to optimise drawcalls, materials and textures, and you'd take a similar approach for targeting low-end laptops.

There is no magic switch that allows poor hardware to render a million triangles at 60fps regardless of the engine. The magic is in a game developer's ability to design, manage, compensate, simplify, optimise and choose his/her battles wisely.
