Long time reader, first time posting...
I recently built a Core i7-based machine, and I am not seeing the performance I would expect from FSX, even after quite a few hours of tweaking. This is not unusual... I don't think anybody is completely happy with FSX performance. It may just be that my expectations are too high, so I am wondering: what can I expect from my system in FSX?
I have the full specs and initial settings below. Here is what I am seeing:
- I typically test with the Robinson R22 (helicopter) around KATL (Atlanta), using the settings below. This is a dense urban area with almost no water.
- Setting either Complexity or Autogen above Dense results in two issues:
Stuttering, especially when panning in an external view. It's really more like "lurching" (fast, then slow) but I believe most FSX folks call this stuttering. I never see anything like this in games: swinging frame rate, maybe, but not this stuttering / lurching.
Graphics artifacts, like severely stretched triangles, especially from trees. This happens with several GPUs, though I have only tested with NVIDIA so far. This doesn't happen with lower settings.
- Both issues are reduced quite a bit using the DX10 option. Does that sound right? However, it is my understanding that DX10 is not intended for full-time use.
- The only add-on I have installed is the Tahiti X scenery from Aerosoft. Flying around Moorea (NTTM) is especially sluggish and shows artifacts; Bora Bora (NTTB) is much better.
- I have tried a number of things mentioned in various forums, with minimal success, so the settings below are really just my starting point.
I would like to see 25 fps around KATL with the highest Complexity and Autogen settings (Extremely Dense), but that may be asking too much. It seems like it is possible from what others have said elsewhere with a similar setup.
If this is already covered somewhere else, let me know. I have looked around and found a lot of advice, but but it doesn't seem to help in my particular situation. Thanks for any help!
- FSX Gold - Acceleration w/ SP2
- GRAPHICS: 1920x1200x32, 25 fps, Trilinear, Anisotropic, bloom OFF
- AIRCRAFT: Medium High
- SCENERY: Ultra High, with 60 cm texture and Mid 2.x for water.
- WEATHER: Ultra High
- TRAFFIC: Medium High
- No fsx.cfg tweaks, though I have previously tried several things.
Intel Core i7 920 Nehalem 2.66GHz
- Mild overclock to 2.8 GHz, on the stock cooler.
- FSX drives the CPU temp to about 65c.
6 GB G.Skill DDR3 1333 RAM (PC3 10666)
- Timings: 9-9-9-24, tried 8-8-8-20 with no obvious effect.
- The motherboard recognizes this as 1066 speed, so I manually bump it to 1333.
EVGA GeForce 8800 GTS 320 MB
- This is at stock speeds.
- Latest driver is installed: 182.50.
- I have tried a GTX 260 with 1.5 GB RAM, with no obvious effect.
- ... though it did speed up Crysis and World in Conflict quite a bit.
Gigabyte GA-EX58-UD3R motherboard
- I have tried disabling speed throttling options, with no obvious effect.
Seagate Barracuda 320 GB 7200RPM SATA
Sound Blaster X-Fi Xtreme Gamer
Antec SmartPower 2.0 500W
- This has two 18A rails.
- This is almost three years old, so I wonder if it is losing watts/amps.
- I don't see any stability issues that might be caused by being underpowered, except those artifacts in FSX (likely unrelated?).
