With the launch of the P3D v2.2 on Monday, I did a clean install with the hope that it would bring better performance to the LM platform while solving many of its earlier reported issues, especially the three ghosts that had been haunting my system since the beginning — namely, stutters, Saitek Flight Instrument Panel (FIP) sluggishness and texture blurriness.
Actually, over the last few weeks, the first ghost, stutters, was in general removed through the increase of the BufferPool to 900 millions as described in Post 234.
The FIP smoothness was also enhanced by assigning the first 2 CPU cores via Set Affinity option under Windows Task Manager. Similarly, the texture blurriness was improved with the AffinityMask set to 252, which dedicated the last 6 CPU cores for the simulator.
Although it still couldn’t be said ideal, P3D v2.1 at that moment was pretty close to what FSX was performing on my rig.
Right out of the box, the new version 2.2 has already reached a new height in terms of smoothness and stability even under maximized settings. FIP smoothness is also enhanced by default, meaning there’s no more need to assign specific CPU cores for it. What a big improvement!
Unexpectedly, texture blurriness is still terrible. Many times, it isn’t getting any better but worser than the earlier version after flying for a period of time. More precisely speaking, the texture becomes extremely blurred when flying away from the range of area or airport where the plane starts.
In addition, autogen objects in far distance, due to sluggish refresh rate, simply disappear. Consequently, the plane ends up flying over a blurred land texture with no autogen objects showing at all.
Based on my last good settings for P3D v2.1, I keep the AfinityMask=252 and PoolSize=900 millions. Then, many commonly known solver tweaks, such as Fiber_Frame_Time_Fraction, Texture_Bandwidth_Mult, TextureMaxLoad, etc, have been applied for the blurriness and autogen issues.
Unfortunately, all attempts are in vain.
Hardware of my system remains the same: i7-4770K CPU overclocked to 4.2GHz; three monitors connected to two GTX 780’s in Surround mode under SLI connection. Besides Orbx’s FTX Global, NA Pacific Northwest and FS Global 2010 FTX, no other addons are installed.
What have I messed up?
Stay tuned for Part 2.
