Low FPS Issue in Rift

I'm posted this on the RIFT forums but wasn't having much luck with responses so figure I'd try here.


So I've been doing a lot of reading to determine what my issue is, is it a driver issue, gpu, cpu or if there is no issue and I just need to suck it up.

Anyways, I stood in Sanctum (main city) today in one spot, kept the same viewing angle, staring at the same scenery with very little moving pieces around me (i.e. players running around). And I wanted to see how fiddling with all the settings effected the frame rate, and I found it pretty interesting. I'm going to put some information below, maybe someone who has a better understanding of computers could give me some insight.

CPU - Core 2 duo at 3.45 ghz, 4 gb of DDR2 800 memory, ATI 5870 GPU - drivers 11.2 cap 3, max res 1680 x 1050.


1680 x 1050 resolution, all sliders to maximimum including AA/AF - 42 FPS

1680 x 1050 resolution, medium settings - 58 FPS

1680 x 1050 resolution, minimum settings - 73 FPS

- This all seems fairly normal, it's what's below that seems really weird to me.

800 x 600 resoluation, all sliders to maximum including AA/AF - 43 FPS

800 x 600 resoluation, medium settings - 57 FPS

800 x 600 resoluation, minimum settings - 75 FPS


These resoluation changes with no FPS change, this isn't normal is it? Is this an indication of something that might provide me some insight into my lower than expected frame rate. And if you says "well you get 42 FPS maxed out that's great" this is a low intensity setting I'm using, on high settings I'm dropping to less than 10 fps while in large groups.

It's the game itself. I know around 8 people (including myself) that have been playing it since release, and ALL of them have been complaining about shitty performance. Three of them just built new rigs too, so it's definitely not a hardware issue.

Simply put, the game was coded by a chain gang of chimpanzees.

ATI 5870 GPU... ATI XXXX.. ATI.. now theres yar problem.. Have the same problem myself, tho mines worse, around 15 fps no matter the setting, all maxed, 15.. all min... 15!

This game is clearly a CPU hog. I found as I overclock my CPU, my performance goes up and up. At 2.67ghz on my i7 920, there are spots in town that I will be in the 20's in FPS, when I OC that to 3.4ghz, I am getting in the 30's in performance and higher.

The other day I was on Vent, and noticed I lost about 10 FPS being on Vent. This leads me to believe that it may like more than 3 cores, that or Vent uses a fair bit of processing power.

I did notice that at 3.4ghz and a i7 920 without vent running, a 2nd 6950 increased my FPS by about 10 again.

Looks CPU limited to me. Probably benifits more from clock speed then anything else.
