Hello, kind of new here on forum and have read alot off the posts.My computer is a HP Pavilian a465c computer 3.00 gHz with 512 mb ram. I run MSX with acceptable fram rates with medium sliders (except autogen) in big cites and get 6-12 fps on ground and 20-30 in air. ok. Lots of freezes and puases while things load though. Jerky motions some times.My graphics is on board intell integrated graphics with only about 64 mb shared memory. Scenery is blurry ground not much texture on ground and can see cars but no roads, railways etc. Aircraft are sometimes blurry, I have my global scenery slider al the way right. Sometimes ac is sharp and not bluury. Sometimes for about 2 seconds I can see sharp great looking ground with roads and everything then it goes back to low texture and blurry.My memory is 184 pin DDR SDRAM, pc3200 . There seems to be a discrepency on HPs website for the product specification for this computer. The web says that the computr has 512 MB installed ( 2X 256 MB) and max allowed is 2 GB (4 X 256 GB) This doesn't make sence that would be 1 Gb. Board has 4 memory slots, two are being used. However, the Mother board spec sheet for this computer on HP web saids up to 4 GB PC32oo/2700/2100 DRR DIMM can be used in the four slots?.Would upgrading my memory to 1.5 or 2 gb help ? Can I mix 256 GB ram (DDR with a new 1 gb module ?My computer also has two free PCI and one AGP 8X/4X slot. Would an inexpensive video card add to my system performing better, and if so, what is a good inexpensive card.Any help would be greatly appreciated.

You can easily increase that to 2 gig, any more would be a waste of time and money. Use two matched 1-gig sticks and DO NOT mix sticks.Your computer would perform better with a dedicated grpahics card. Limited choice as you need 256 meg or 512 meg to do FSX justice. 7600GS maybe?Allcott

There are two tracks involved here - memory and more powerful graphics capabilities.Memory - nothing (and I mean nothing) adds more punch to running applications than increasing your system memory. Windows XP Pro can handle up to 4Gb of RAM (see the MS site for specs). The key here though is to match the memory sticks as closely as possible to the specs of your motherboard. If your bus runs at 400MHz and you want ultimate performance then get memory sticks that can operate at 400MHz. Make sure you purchase quality memory. I recommend Corsair - especially if you have DDR2 requirements. Their sticks are more expensive you you'd be amazed at the results.More powerful graphics capabilities - Purchasing a more powerful graphics card will not increase the performance (speed) of FS. I stepped up to an NVidia 7800GTX PCI Express with 512Mb of onboard memory and it didn't increase my frame rate at all. What it did do was improve the graphics handling functions of FS so that the display was amazing.fb
