Can you use MAX shadows at Road Atlanta?

[Frankalexandre]

I can maximize all other settings but must keeb shadows at high. If i set it to MAX, my fps drop to 30/40 when passing the first and other bridges.
Anyone? Please post PC spec.
Mine:
Q6600@3ghz
GTX285
4g Ram
Windows XP.

I have every thing max at 1920x1080 and it does not drop below 140.

ASUS PT6 Deluxe
I7-920@ 3.1 Ghg
Radeon 4890 Not Over clocked
12g Ram
VISTA Ultimate 64bit

Mojo I have similar rig but with 6gig ram. does the 12 gig make much difference for these games?

[PEK]

Hired Goon not at all.

32 bit games like Race On (and most other games) are limited to 2GB of operating system memory, even in a 64 bit OS.

Yes, the only benefit to having all that RAM and a 64-bit OS is that each application gets it's own 2GB address space (not including video RAM as with 32-bit OS) and you still have plenty of memory left for system processes.

The 4GB limit in a 32-bit OS includes video RAM in the equation.

32-bit OS with 4GB RAM and 2GB video RAM (SLI) = only 2GB available system RAM.

64-bit OS with 4GB RAM and 2GB video RAM (SLI) = all 4GB still available for the system.

So even if your games are 32-bit, you do get a nice amount of extra headroom by having a 64-bit OS with 4GB or more of RAM.

I have read a post by someone who seemed to know what they were talking about that this isn't true I'll see if i can find it.

EDIT here we go

I can confirm he's right. I have a 1GB video card but 3.25 GB of useable physical memory on my 4 Gb XP 32 bit OS PC.

You can easily google it. It is true. The 4GB limit includes video memory. It is not a 1-to-1 relationship, but it is true.

But since you would rather trust "some guy who seems to know what he's talking about", here's a snip"

The 4GB limit refers to total addressable memory space and not just the RAM installed. It’s a total made up of system RAM, graphics RAM, PCI memory range, ACPI and a few other bits and pieces. And if you think that your system RAM is the only significant factor, think again. You can buy graphics cards fitted with 1GB or RAM, and if you wanted (and had the spare cash!) you could fit three of these into a system. There’s not a 1 to 1 relationship between graphics memeory consuming system RAM, but the larger the memory, the more the card sets aside for itself. Now that 4GB limit doesn’t leave you a lot of space for system RAM.

For more information, check out an excellent post by tech guru Mark Russinovich. Here’s a small extract from Mark’s blog:

The consumption of memory addresses below 4GB can be drastic on high-end gaming systems with large video cards. For example, I purchased one from a boutique gaming rig company that came with 4GB of RAM and two 1GB video cards. I hadn’t specified the OS version and assumed that they’d put 64-bit Vista on it, but it came with the 32-bit version and as a result only 2.2GB of the memory was accessible by Windows. You can see a giant memory hole from 8FEF0000 to FFFFFFFF in this Meminfo output from the system after I installed 64-bit Windows.

This was the point I was trying to make

And if you read the replies to the article

All I know for sure of course is from my own PC. I have a 1GB graphics card but have the same free useable memory as if I had a 500 Mb card or a 250 Mb card.

none released yet, public at least, guess he meant Road America
