Windows 7 64 Bit and TC
Read 4486 times

Hi all,

I am looking at upgrading my system to 64 Bit Wndows 7, primarily to get more grunt out of TurboCAD. Has anyone done this that can give me some advice etc?

Does TC work well on 64Bit? I was thinking of upgrading to around 6-8 gig of RAM, will this be utilised by TC18 Pro Plat?

Any help would be greatly appreciated.

Apparently not, it works as a 32 Bit in the 64 bit environment. I find that the multithreads have to be reduced to avoid untimely "out of memory" issues.

Perhaps workstation has the grunt your after something with Intel 3 Ghz processor with higher ram than 2 GB and graphic card that used for cad applications.

Daz, Ive heard that 4 threads work well but 8 dont?

I'm running with Windows 7 64 Bit, 4 gigs of RAM and a 2GHz Dual Core Processor with a HD Graphics card and everything seemed fine with TC17.  I have seen improvement, but I upgraded from a slower single core system.  I Haven't tried the Multithreading in TC18 yet to see if it improves anything.  I Know TurboCAD is a 32 bit program and Windows 7 64 Bit seems to handle 32 Bit programs well at least I haven't had many problems.  If You're upgrading, increasing system RAM and video RAM are good ways to improve performance in graphic intensive programs.  I Think The Only way to take full advantage of Windows 7 64 Bit is for TurboCAD to actually be a 64 Bit program.  I don't know if that is planned for TurboCAD or not.

Yes, i use 4 threads and no more.......8 are available but crashes occur more frequently with using any more than 4...

Now have TC v18 on XP SP3 - 4G installed ram - DX58SO MB, i7-920 uP...

This has a total of 8 threads - TC v18 seems to use them all with no problem.

I also have recently built a Win 7 64bit machine (same MB, i7-930 uP, 6G ram) but haven't yet tried TC v18 on this computer.

Does anyone have a comparison (same machine - dual boot) of rendering times w/TC v18 on 8 threads (XP) and and on 4 cores (Win 7)...?

Thanks...

Just a comment on Quality rendering using multi-core. If you set your system to Raytrace Full (which is not the default) you should be able to see "banding" as your rendering appear indicating this is working.  Of course you can also use task manager but that can be a pain when rendering.

Dave,

In XP with the configuration I posted earlier, I do see the "banding"; and; the rendering is considerably faster (nice improvement) - can also see the use of eight threads in task manager (dual monitors).

Still wondering how this multi-core speed increase works for v18.0 w/ Win 7 SP1; from reports in this forum, the use of more than four cores (threads) results in instability.

Can always try it here... but on how many machines can I load my one license of V18.0...? My Win 7 computer is another desktop; but for "customer visitation" requirements, I usually also put TC on my ancient (circa 2003 XP SP3) laptop.

Thanks.
