Display driver plays an important part in Flight Simulator. How to install it or uninstall it will impact FSX’s performance and stability, especially when switching from NVIDIA to ATI or ATI to NVIDIA.
It is widely known that even after a program or a driver is uninstalled, many “tails” of it will still remain in the system. It is therefore necessary to ensure that a display driver will only be installed or updated onto a clean environment at all time.
Following is how I update the ATI display driver from 11.3 to 11.4 Continue reading →
I’ve given up the card after using it for 5 days. It is hardly conceivable that such a high-end graphic card is a crap to FSX!
Indeed, it has pros:
1. Better depth of field compared to my previous ASUS Matrix HD5870
2. Framerate is about 3 to 5% more than Matrix 5870
3. It generates less heat and relatively quieter
However, two intolerable problems with this card are:
1. Texture become incurably blurry
2. FSX crashes frequently
In the past few days, I have tried all different tweaks, including BP=0, RejectThreshold, etc, etc. After a lot tweakings, I can manage to have it running FSX smoothly; but, blurry land texture was unpreventable and the worst thing was: FSX crashed uncontrollably.
Just purchased the newly released ASUS GTX580 Direct CU II card to replace my current ASUS HD5870 Matrix Platinum card.
I bought the HD5870 for two reasons:
* allows connecting to 3 displays (I only have one currently, however)
* GTX480 was reported very hot and noisy.
Although I am getting average 41 FPS in most sceneries with the HD5870, some micro-stutters and under 20 FPS performance within dense areas reamin the barrier for my system to break. As nVidia card is generally agreed to be better for FSX and reviews of GTX580 show that the new card is now cooler and less noisy (especially the modify Direct CU II version), I decided to wait no more to find out the true side of it myself.
Following is the fsx.CFG I used for my GigaByte Nvidia GTX285. Nvidia driver used is 22.214.171.12496 with nHancer 126.96.36.199
Average framerate achieve is 39 on my Dell 30-inch.
AffinityMask=14 // 14 for last 3 cores — No need setting to 15 for 4 cores
RejectThreshold=126976 //124Kb = 126976
ALLOW_SHADER_30=1 // === Important to assist PoolSize ===
HIGHMEMFIX=1 // Fix errors of black squares around lights whilst panning around
STALE_BUFFER_THRESHOLD=1024 // 1024 in KB
TextureMaxLoad=12 //Use multiples of 3 ONLY but may induce stutters
