Poor performance on good rigs (I think)

Yeah. Most of the original missions ran pretty well on a GeForce 6600gt.

 

There are a couple of things to consider though...

 

There are very few hard limits in TDM so mappers are free to create maps with more polys, longer views, more lights, more AI, etc than most players' systems can handle...

Newer GPU's have trouble with ARB assembly language which is what TDM's shaders are currently written in.

If enough people nag nVidia and ATI about it, perhaps they'll improve their ARB handling for the latest hardware...

 

The lights are most reliant on memory and PCIE bus bandwith, if you don't have at least dual channel memory, PCIE 2.0, and 128-bit GPU memory then your system will struggle.

Many laptops have decent GPUs but lack memory bus specs and especially lack GPU memory lanes ( the typical configuration is still 64-bit). For desktops we typically see 256-bit for upper mid-range hardware

and 384-bit or even 512-bit for highend hardware.

I remember back around the Radeon 9700 launch, that the Beyond3d forums were filled with folks who hoped that GPU manufacturers would stop making 64-bit GPUs and switch to 128bit as the new low end,

alas that never happened because interconnect technologies don't improve as fast as wafer tech. It looks like nvidia's next GPU generation might have the memory on the same wafer as the GPU and with have

thousands of bits of interconnects.

 

Still, there are things that can be done make TDM more friendly to modern GPUs and there are a few Doom 3 projects out there that are continuing to make progress on that front.

      Finally got my PC back from the shop after my SSD got corrupted a week ago and damaged my motherboard. Scary stuff, but thank goodness it happened right after two months of FM development instead of wiping all my work before I could release it. New SSD, repaired Motherboard and BIOS, and we're ready to start working on my second FM with some added version control in the cloud just to be safe!

      I've updated the articles for your FMs and your author category at the wiki. Your newer nickname (DeTeEff) now comes first, and the one in parentheses is your older nickname (Fieldmedic). Just to avoid confusing people who played your FMs years ago and remember your older nickname. I've added a wiki article for your latest FM, Who Watches the Watcher?, as part of my current updating efforts. Unless I overlooked something, you have five different FMs so far.

      I've finally managed to log in to The Dark Mod Wiki. I'm back in the saddle and before the holidays start in full, I'll be adding a few new FM articles and doing other updates. Written in Stone is already done.

      You cannot receive PMs. Could you please be so kind and check your mailbox if it is full (or maybe you switched off the function)?
