TIP.. Improve frame rate by 100% - 200%

[deadsmell]

same here, I tried this yesterday hoping that someone had found a way to make it work with xp, but it does not work for me at all.

 

el waste of el time.

 

Edit: yeah I just got member status!

Oh of course I forgot to mention that I was referring to the DCS affinity tool.

 

Which of the 3 tools did you use?

 

The best way to test to see if it will work is by setting the affinity of DCS.exe manually. Try loading up a mission, alt-tabbing to the desktop then using task manager to set the affinity of dcs.exe to all cores. Once you alt-tab back you should see an improvement in fps. IF you do not see any improvement in fps, then none of these tools will likely help you.

 

Another thing to check is whether or not you have vsync enabled. If you have vsync on, then your FPS will never be higher than the refresh rate of your monitor, which can make it difficult to tell if the affinity trick is working.

Ok, just tested Instant Action with and without the affinity tool. At first I thought I actually had some sort of a result with total CPU load hovering at around 30+%, but then I realized that I had some processes running that would account for the ten or so percent increase over the 25% load (maximum for single CPU). Sure enough, when I ran without the Affinity tool I got exactly hte same result (was only checking the CPU load, not FPS). The affinity tool did work since I saw the load bounce constantly from one CPU to another, but it didn't manage to utilize the extra CPU power. If anything, there was slight extra load from constantly switching the execution from one CPU to another, which is frankly pretty much what I'd expect to see when making an inherently single-CPU application run on several cores. Any ideas about how I could get the FPS increase?

 

In order to determine whether it achieved its goal (getting an FPS increase) would be to monitor FPS not CPU load. I understand your skepticism as I also can't work out why this trick works... but it does under Vista.

 

Keep it simple.

 

Load BS.

Start a mission.

Bring up FPS counter.

Pause mission.

Modify the affinity (I use SetAffinityII)

Ignore the CPU load. Doesn't matter what runs where if performance increases.

Go back into BS.

Note increase in FPS just on the paused screen.

 

When I do that I'll see an increase of 15-20fps the moment I go back into BS every single time. If I alt-tab back out and change it back to core 0, performance drops back down. It's very repeatable and very noticeable.

I have this tremendous fps increase only with Full Screen. Only little change without Full Screen.

I use DCS:BS affinity tool and of course Vista.

Ok, it appears that full screen might have done the trick. I'll have to do some more testing later, but it appears I may finally have got this working. Nice tip, Yossarian. Anyway, it would be really interesting to find out what's really going on.

 

I noticed that the FPS curves are pretty similiar, one is just constantly higher than the other. This would indicate that the game is absolutely CPU bound in all the measured circumstances, which is within the limit of possibility, but somewhat unlikely. Then again, if the FPS increase comes from a huge boost in CPU power, why isn't the CPU working any harder? Anyway, I'll have to do some more tests when I have the time.

Hasn't this already been beat to death in another thread?

i installed vista64 on a new partition and run BS through the affinity launcher and defo notice a difference

 

the ONLY game i own that runs faster under vista than xp32

 

pretty chuffed with it
