T2D dev

I just started work on a 2D game built on SDL when, looking into collision detection, I ran across a .plan for T2D. To make a short story shorter I purchased a copy. I do have some questions.
1. I haven't seen any reference yet to font handling. If T2D doesn't do it its (probably) no big deal because I already have that part written (using SDL TTF libraries)
2. Discussion I've read seems to be mostly about retro gaming and the demo ran slower than molasses on my mac (G4 powermac). So slowly there was no keyboard input as far as I could tell. How much hardware is required to get reasonable performance for something large?
What I'm working on is intended to be a large gameworld RPG -- not that many players as I'm aiming for tabletop-style gaming but with a *large* environment having numerous objects.
T2D offers *lots* more than I was planning on putting in -- I'm just trying to get an idea of the bounds.

so far I've been pretty impressed with T2D, I should probably try it on my old pentium2 400 see how it performs there. On that machine BlitzMax crawls at 2-4 FPS in much the same way T2D does on your G4.

Using fraps to get the framerate on my athlon1200 Geforce3 combo, I get 150 - 180 FPS in the shooter demo. What kind of 3D acceleration does your G4 have?so far I've been pretty impressed with T2D, I should probably try it on my old pentium2 400 see how it performs there.

On my EPIA ME6000 (performance something like a PII400, with built-in S3 video), the demo chugs, but is playable. Even Think Tanks doesn't run on this machine, so I'm betting there's a problem with your Powerbook.

Sounds like you don't have OpenGL hardware support, but that also seems weird. It tries to simulate hardware with software, thus, it runs as slow as snails even on a fast machine. Check your drivers and the status of OpenGL support on your graphics hardware.

I looked through the reference guide and no mention of text. Am I missing something or will I need to integrate the code I've already written?
It also looks like the script interpreter fails silently on errors? Or am I missing something?

Its the shooter demo. I'll have to double check the G4's video card tomorrow. I thought it had OpenGL support, but I don't recall the card. Its reassuring to hear that it is at least playable on older hardware.I looked through the reference guide and no mention of text.

Another data point...I have a new Macintosh Mini which has the G4 processor and ATI Radeon 9200 with 32MB. T2D runs fine using the OpenGL drivers. I get 90-100fps. Best Regards,

Had some problems with the tex flashing in windowed mode, But I only recently installed the Beta Nvidia driver...i suspect thats the cause.

I ran it on a 733 meg celeron with a geforce4 mx PCI and stayed above 60fps.(about 75 average) Had some problems with the tex flashing in windowed mode, But I only recently installed the Beta Nvidia driver...i suspect thats the cause.

Ack. Sorry, somehow that got posted twice. To Jeff: I'm still learning my way around GG.

I actually had an odd issue with the shooter demo, in that it ran fine, framerate-wise, but hiccuped every few seconds, as if it was loading a bunch of data from the hard drive or something. I've got an AthlonXP 2800+ OC'd to 3200+ with a Gig of RAM (about 2/3 of that is free), so I'm wondering if I'm missing something.
