I am not happy Hello and good morning everyone X-plane 10 demo was downloading last night while flying a couple legs from the Caribean tour. Once downloaded, I realized that no installation was required, which is cool. SO I launch the thing. Now, before I go any further, let me provide you with the specs of my computer: :( :( - Intel i7 core - 24 Gb of RAM (yes, 24) - ATI Radeon HD5870 With almost everything turned on to medium and high in X-plane 9, I get easily 40 fps. In X-plane 10, I spent 30 minutes trying to figure out how to NOT have a slideshow. OK, I don't understand how people can actually run the sim. I had to turn down the texture res to Medium. With BLUE SKIES, I can NEVER get more than 18 fps, with settings at medium-low, and with HDR, which does not seem to affect a lot at the FPS level, which is good news. Shadowing is horrible. I tried every setting, and again, removing the shadowing, I gained about 1-2 fps. TRees to sparse, AIrport detail and all other settings to default. "what the hell" is what I'm thinking. I was reading the posts on the internet on the X_plane developer blog, and they said many times that if good performance on X-plane 9, then X-plane 10 would be similar or even better!!!! Let's just say that, to even REACH 20 fps, I had to remove traffic completely, and set everything to blue skies. Setting clouds in there, I go below the mark of 10 fps. I just don't get it. I tried different resolution, because I thought that maybe my three monitors configuration was the problem, so I set it to 1 monitor in 1980x1080-16 bit. Same thing. Gainned about 1 fps overall. I am REAAALLY Disapointed. Now, I have not updated my display drivers for a looooong time, but I can't believe that this could actually be the solution. How would display drivers suddently give me the missing 20fps to reach 30fps ? OH I forgot to mention something, this is not even in KSEA, this is at a nearby airport in the coutry side near KSEA, cause KSEA... forget it. Slideshow. and there are bugs all over the thing. I flew over the coutry side.. there are houses line up in the middle of the forest... with no roads (I"ll take screengrabs when I can). Weather looks good....but to me, it is unusable the sun looks amazing when it reflects in the water. I will update my display drivers tonight and report back. In the meantime, id be interested to see what people have been getting as fps, WITH and WITHOUT HDR enabled. OK guys, If you are going to run XP-10 without clouds and without HDR... might as well stay with XP9 ???? that's what I think. Slideshow, even with a new system so they better improve... I don't even want to think of using the CRJ at the moment. Thank you and most importantly... good luck ??? here's the post I'm referring to, only 2 months old, and with the same card that I have: the performance he states are definitely far from what I am getting: http://www.x-plane.com/blog/2011/10/x-plane-10-and-gpu-power/ Patrick
