General Performance Issues

Hi, 

As you can notice, I am not a technical guy but I am very frustrated because I got a, suposed to be, "top of the line" PC just for Flight Simulator X and I have a lot of problems with it, I only have the FSX installed and nothing else, the specs of my PC are:

-Processor Intel® Core™ i7-4770K Processor (4x 3.50GHz/8MB L3 Cache) - Intel® Core™ i7-4770K (20% OC)
-Motherboard MSI Z87 G41 PC Mate -- 1x PCIe 3.0 x16, 2x USB 3.0, HDMI
-8 GB [4 GB X2] DDR3-1600 Memory Module - Corsair or Major Brand **FREE Upgrade to Corsair Vengeance**
-Video Card NVIDIA GeForce GTX 770 - 4GB - Single Card
-Power Supply 850 Watt Corsair CMPSU-850TXV2 80 PLUS Bronze
-Processor Corsair H60 Liquid Cooling*
-Primary Hard Drive 128 GB ADATA SX900 SSD -- Read: 550MB/s, Write: 520MB/s - Single Drive
-Data Hard Drive 1 TB HARD DRIVE -- 32M Cache, 7200 RPM, 6.0Gb/s - Single Drive
-Optical Drive 24x Dual Format/Double Layer DVD±R/±RW + CD-R/RW Drive - Black
-Sound Card 3D Premium Surround Sound Onboard
-Speaker System Creative Inspire T3300 2.1 Speaker System w/ stylish design + quality performance
-Network Card Onboard LAN Network (Gb or 10/100)
-3 x Monitor 24' ASUS
-Windows 7 - 64-bit

My Problems are:

-Low graphics resolution
-Sometimes I get a message of LOW Memory
-The runway lights including the ILS lights and beacons are totally blurr.

I am really frustrated, please help me out, I don't know if I need to change the cfg or what and the purpose of this is to build a home cockpit with Saitek Proflight Hardware but I am totally frustrated.

Than you so much in advance

Please do not install Bojote's tweaks on that nice system!!!  It will create even more problems!!  If you just have FSX installed, your FPS should be about 290-300. You are attempting to run 3 monitors and I think that is your performance problem.  You cannot have high FSX settings with 3 monitors.  Still it should run satisfactory if you just have the default FSX.  Check out the AVSIM FSX Configuration Guide located under Hot Spots to the right of this forum.  Use those settings for your fsx.cfg and your NI settings.  Also, as indicated in the AVSIM Guide, make sure you have the highmemfix=1 under the Graphics section of your config.  High settings and unlimited fps will cause blurriness. FSX just cannot render fast enough to render the graphics.  This will happen even if your fps are at 200 or 300 fps.

I personally run a disk based RAM cache, which allows for faster loading of textures. Just install it, set the cache to the drive you have FSX, and it will help to speed up texture loading by using some of your RAM to temporarily store textures.

Thanks.  Hopefully it will help the OP.  I don't have this problem as I run FSX on an SSD and use conservative settings.  I would be interested in knowing how well this cache program works.  I don't think anything can save high settings.

You have a very nice system there and it should run FSX really well.

You are not being very specific here, what do you mean by "low graphics resolution"?

I assume that you are running FSX at the native resolution of your monitor(s)..

 

Does it all work well with a single monitor, and does the problem occur when you go to three??

 

Give us some more information and maybe we can help.

 

Also are you using nvidia Inspector to set the graphics settings on your monitor(s)?

Best regards,

 

For the kinds of files that FSX uses (mostly small texture files), these will use the 4K read speeds. Mesh files are read with sequential reads as they are big files.Without the cache, I get 25 MBps read speeds. With the cache enabled, I get 1 GBps read speeds (not a typo).

 

My settings aren't too high, but when I did put them too high, I had texture loading issues (blurries, or the gray DX10 texture)

 

There is also a config tweak called SWAP_WAIT_TIMEOUT which is said to reduce blurry textures. I have mine set to 2, instead of the default of 30. The lower the number, the less blurry things will be.

HI,

I have tested Primo Cache and I have noticed some improvement in texture loading and general smoothness. Just one question: do you use default settings on Primo Cache ? From the post above I assume you use 4kb blocks. I also assume you are using "read only" strategy" ....How much RAM are you reserving to be used by Primo Cache ? I have tested it on a 2 hrs flight (using NGX, UTEur, FTXG and ASN with FEX2 clouds and sky textures @DXT5/1024) and I have seen on the Cache control panel that there has been a Cache Hit Rate of 60% (meaning that out of the total readings from the FSX disk, 60% were read from the cache). I was expecting something more in terms of hit rate, considering that FSX is installed on a separate SSD from the OS....what is your experience on this ? How much hit rate do you usually have ?

Thanks

These are the settings that I am using:

 

L1 cache: 4096 MB (reduce if you don't have much RAM. Say, if you have 4 GB or 8 GB, try 1024 MB or 2048 MB)

L2 cache: disabled

 

Block size: 4K (lower number, better performance, but more RAM needed as it has a bigger overhead)

Strategy: Read & write

Defer-write: 10 seconds (said to reduce writes to SSDs and improve lifespan). Another thing, if the cache is full, it will empty itself (depends on the number of seconds you specify). .

 

My hit rate was lower than 60%. Around 25%. Probably depends where you fly. Then again, I just tested it for 5 minutes, and not a whole flight. Remember, it only reads from the cache, whenever it needs a specific texture. If say, you flew in an area with a desert shortly after takeoff, but never flew over a desert for the remainder of the flight, then it would not read the desert texture from the cache (less usage).

Jeff Thomson

Thanks...

Why use Read and Write Strategy and not Read Only ? I assume data are only read from the FSX disk, there is no writing action, unless my assumption is wrong.

I'm not sure. You're right about setting it to read only. I should change that.
