DCS and overclocking GPU's

[speed-of-heat]

Your Mileage May Vary - Not suggesting you do this just reporting my findings.

 

So I like everyone else have been OC'ing my GPU, and doing so with the usual perf bench marks which absolutely beat the heck out of the CPU and GPU... so I had a modest overclock on my GPU of 120mhz stable which took me to about 1987Mhz in game. This was nice.

 

 

I then monitored the GPU utilisation and it was round about 60-70% which made me think how much headroom was there in the performance of my GPU before stability was impacted running DCS, after lots of incremental testing I got up to 180Mhz, giving me 2012-2025Mhhz in game. running at 70% fan speed and 70-80% GPU util giving me 70 degrees C GPU temp...

 

That's quite a lot of extra "eye candy" ...

I dont think that you saw any mayor increase in 3D when you have been CPU limited before and after overclocking.

 

When your GPU runs at anything below 98-100% load in uncapped fps mode you are CPU limited.

 

 

You can, however, crank up your LOD until the GPU gets close to 100%. That would yield some eyecandy with the same CPU performance..but also at the cost of more heat.

 

 

Measure your fps average before and after overclock. I doubt they differ if the GPU doesnt hit close to 100%.

 

In the end, what counts is perception and immersion. If you think it is better, IT IS better :thumbup:

Whilst I didn't gain FPS I'm in VR and it gave me a lot more consistent frame rate, with more eye candy turned on.. you will note I didn't say I got extra FPS
