Overall the DEMO runs smooth, but there is some points where fps goes down all the way from 75 constant(v-sync) to 30-40 for no apparent reason and then it goes back to normal again. I checked all of my options, i tryed to set AA off/on, I even lowered the ressolution and game details but still the same. I know that my CPU bottleneck, but i never had any of those issues in the so called "most demanding" games like BFBC2, Crysis or Crysis 2 on those titles my gpu usage is always hovering around 85 to 99% and in Duke DEMO is around 25 to 35% GPU usage even if every possible setting is turned all the way up with vsync off. One of the spots i saw that was at the begining where you are in a corridor and watching how some soldiers shooting the boss(who you fight later on) and the other spot that i saw that is at the second level(desert) where you run out of fuel and you have to go found some.
The demo is a really poor compiled demo for PAX last year, all they did was release that to us, so I wouldn't worry too much, it actually drains the hell out of my cpu to run the demo and I notice that dip at that point too, my cpu is a bottleneck :< The actual game should run fine.
CPU is bottlenecking your GPU ? I reaaalllly doubt that, I just finished a run (1920x1200xMax) and I noticed the CPU graphs on taskmon.... It uses about 22% in a heavy combat scene. I would even go so far as 15%, but i'm downloading torrents in the background & other minor stuff as well.
If you're directing that to me, I've tested it already, my benchmarks differ by a large margin depending on my cpu clocks
Not having any issues with the demo, get around 40% gpu usage across all cards and the cpu usage seems incredibly low, like 7% maybe. Admittedly yes the game is nowhere near as graphically demanding as some other titles, but the Unreal 3 engine has always been incredibly efficient. As for fps drops etc game runs fine here no issues what so ever, no fps drops, using 275.36
It doesn't matter ppl... it was my mistake(CPU bootlenecking GPU ot backward... never mind) no need to make drama out of it. Anyways... i hope the final game to be nice(on every aspect)
Looking at what others are getting for their usage, I think it's time I upgrade some of my old parts :giggle2:
I noticed that the Steam process hogs a full core (25% on my quad) while the demo is running, while Duke himself uses around 2 cores. This might account for any performance drops on dual core systems, as the steam process is stealing performance. Hopefully this is fixed for the final release.
http://benchmark3d.com/duke-nukem-forever-benchmark/2 Check out the cpu benchmarks... it seams the game is badly optimized... it simply run almost the same if you have 1 or 4 cores... i think we found the source of the problem
Still getting the high CPU utilization, the only noticable effect is that I can't sign in to multiplayer with that option disabled.
