As explained in Post 90, BufferPools could effectively reduce stutters on some systems. Actually I was quite happy with its value set to 4,000 for a long time, until recently I upgraded to my current hardware on which FSX seems no longer benefited from it.
My Prepar3D V2 platform, on the other hand, reacts drastically different under the new 3-monitor setup. Stutters are virtually removed when Continue reading
RejectThreshold is a command that instructs the CPU to bypass the bufferpool when a specified amount of graphics data is reached. Before that threshold, all data are kept sending to the bufferpool.
This function can be used in association with the PoolSize command to improve system stability.
Autogen has a default texture buffer of 4 millions. Properly increasing or decreasing this buffer can effectively reduce stutters, especially while the aircraft is in turning.
This function is not by default present in fsx.CFG. To alter the value, one can add the following lines in fsx.CFG; and commonly used values range from 1 million to 15 million (or even higher) in 1 million increment.
