Although the result from the First Run was good, the ultimate goal is still to push the Image and Autogen Complexity of my FSX system to the maximum while having all flights running as smooth as possible.
As expected, when settings of Scenery Complexity and Autogen Density were slided to Extremely Dense, stutters became obvious even though overall framerates remained relatively stable around the preset level of 39.
For this tuning, most of the test flights were taken place in Darrington Mun 1S2. The place is ideal to help evaluate the balance between image complexity and fluidity of a system as autogen objects in the area are so abundant.
Basing on the fsx.CFG from Part 3, followings are the tweaks (including those from Part 3) that I applied after repeated testings:
Amongst all the tweaks, [BufferPools] is the most important part to the ultimate performance result. In addition, TERRAIN_MAX_AUTOGEN helps a lot by reducing autogen objects too.
Actually, setting the PoolSize value to “0” also renders a comparable result similar to setting the value to 4000. The 4000 value is eventually used because it doesn’t require the additional ALLOW_SHADER_30 command. (See my earlier post regarding BufferPools here.)
In fact, there are still a few more tweaks could be further tested, including:
However, as the overall performance is quite good, so I call it a day for now. Nevetheless, will keep testing my exisiting setup with unapplied tweaks above.
Proper tuning of Display Card is CRITICAL to the final result.
