Re: Questions about CPU stuff...

We can not control max CPU usage in an easy way.

100% CPU usage should not block your mouse or prevent from closing the game. Does it really happen?

It would be good to run that in a second thread, but amount of rework is huge. Doubt this is reasonable for us.
It realy does make ur system unstable and u can't do anything at 100% usage of cpu ure screwd

Have you cleaned out your CPU cooling recently?

I don't see how that can be the case. Operating systems like Windows and Linux are multitasking and preemptive, so just because your CPU is busy 100% of the time doesn't mean it is blocked on a single application. Your operating system's scheduler will regularly switch to different tasks (such as moving the mouse) even when one application is trying to use 100% of your CPU. My CPU is often at 100% when encoding video/audio, and although it does reduce response time slightly, it's still perfectly usable.

The only way to achieve what you described is to set the priority of KaM Remake to realtime in task manager. This means it has maximum priority over every other application, and if it tries to use 100% of your CPU is will completely lock up your computer.

A frame rate limit option would be a good idea (especially for those players who don't use VSync). But as Krom said it's not high on the priority list.

Ye ye thanks for adding frame rate limit option to todo list

Also it seems that cpu cooler is too weak to make cpu temp stable and it goes up every 1C* like 10s

So I have 2 options:

Buy bigger fan

or

Change cooling to water one

Can u tell me wich one would be a better choice?

Re: Questions about CPU stuff...

just buy a bigger fan, it is cheaper and you have no risk of water leaking.

Re: Questions about CPU stuff...

In my PC I care about noise. Bought a much bigger cooler with a couple of big low-RPM fans :-)

Re: Questions about CPU stuff...

Does it matter if the cpu is from amd or intel because KaM Remake doesn't use many functions, but there is diffrence between performance in tests

Re: Questions about CPU stuff...

KaM Remake can be seen as a general purpose app. For such apps there could be a subtle difference because of hardware implementation, but usually it is negligible compared to all the other possible differences, such as clockrate, L1-L3 cache sizes, RAM, GPU, HDD, OS, Drivers.

CPU brand / model might matter for specialized apps whose main purpose is data processing and which are heavily optimized for specific instructions sets and cache sizes. You might look into CPU comparison reviews, where they are put through exactly those tests.
