screen resolution making a huge difference

Recommended Posts

Hi everyone, In order to save space on the desk in my apartment, I recently swappede out my 23" 1920x1080 moniter for my older 17" 1280x1024 moniter. I bought the bigger one a year ago and had a GTX 260 for my GFX card. I only noticed a 3-4 fps drop on the moniter. Over Christmas, I purchased a factory OCed GTX460 by ASUS. When I launched FSX, I only noticed a 3-4 increase in fps. I didnt expect much becasue I always heard on here that FSX was CPU bound. However when I recently switched moniters. I get a 10+ increase in fps. I can now play FSX with the same settings but avg. 30 fps and holding steady. I can also use full HD enabled textures from REX. On the bigger moniter, REX would bring the sim to its knees. Anyways, My question is this; IF FSX is so CPU bound, how come I noticed a slight drop going to the higher resolution but a HUGE increase reducing my resolution? I would think that I would have noticed a huge drop going to the bigger moniter since i was sporting a GTX 260. Or get a bigger increase when upgrading to the GTX460. Its funny how every other game I played saw huge increases when switching GFX cards and not one decrease in switching to the bigger moniter.

At 1920x1080, your system is computing 58% MORE pixels than at 1280x1024. Got to have an effect!AR

I understand that. I just don't understand how I could get such a small decreas in perf from going to the higher resolution on my old card and not seeing an increase in perf with the new card. Shouldn't the perf dropped massively when going to a higher resolution with the old card? So basically....why am I seeing such an increase at the lower resolution with the new card and not at the higher resolution? If my old card performed pretty much the same at both resolutions then I should see the same increase on both resolutions with the new card right? Not the same on the higher and a huge increase on the lower res. It's like the 460 only matters at a low resolution and it looses it's gains when going higher....exponentially.

You've got me! But the end result is the combination of CPU plus the GPU, sorting it all out between themselves and then squirting the image out to the monitor. Obviously some combinations work better than others. Some marriages work and others hate each other!AR
