Has anyone tried this extremely cheap APU for quakeworld? Only USD$50 and both the CPU and GPU components are unlocked and overclockable.

Would love to see how it performs as it could be built in to a very low cost ultra portable QW LAN PC in something like this:

I'm pretty sure that could do 308 FPS easily. I don't know if it could reach the 1000+ fps that you're used to. The question is can you really notice the difference between 308 fps and 1000+ fps?. Have you ever done a proper test?. We should make a script that can randomly switch between 308 and 1000+ fps and then ask the player to guess!.

The bottleneck for Integrated graphics is the memory and so some users will buy the fastest memory possible.. But I'm not sure if this is wise as an APU has a reduced number of shaders to match the reduced memory bandwidth..

When I needed to travel I would place my motherboard with all the components still plugged in, into the box that came with my motherboard. Very compact

Dirtbox had a post here (that I can't find) explaining how he can even notice a difference between 1001fps and 1155fps.

hah, personally I can easily spot difference between 308, 616 and 1001. Not sure about 1001 vs 1155 as never tried it.

Interesting... Does it feel different or look different?, or maybe both? Are the tear lines more noticeable?. Or does it just feel less laggy?.

Personally I can't even get 1000 fps to test it myself...

I made a placebo.cfg.
Just change var1 and var2 to the variable you want like cl_earlypackets, sys_yieldcpu, sys_highpriority or whatever may be the case.

Quote:
alias var1 "cl_maxfps 308"
alias var2 "cl_maxfps 1001"
set_alias_str var1text var1
set_alias_str var2text var2
alias placebo "if $rand > 0.5 then set choice 1 else set choice 0; if $choice == 1 then var1 else var2; echo Press 1 for $var1text or 0 for $var2text"
alias count "echo right: $right, wrong: $wrong"
alias correct "echo correct; inc right; count"
alias fail "echo wrong; inc wrong; count"
alias placebo_restart "set right 0; set wrong 0; placebo"
placebo_restart
bind 1 "if $choice == 1 correct else fail; placebo"
bind 0 "if $choice == 0 correct else fail; placebo"

I just did a test using your script, Matrix!.

I can't hit 1000 fps but I found that I could still tell the difference between 308 and 616. I noticed that at 308 fps things seemed slightly more blurry than at 616. But what's interesting is that I then tested between 72 fps (my monitor's refresh rate) and 616 fps and I couldn't tell the difference at all.

And in terms of lag/latency all fps settings felt the same to me.

So it seems that if your fps is multiples of your monitor's refresh rate then you won't notice the difference between fps settings. But if your monitor's refresh rate isn't multiples of 77 (QW physics) then things may start to seem a little blurry with lower fps settings.

This does make sense when considering my earlier findings that if I used 77 fps on a 72hz monitor then everything would seem jittery. But if I used higher multiples of 77 then things would start to smoothen out the higher I went. Yet if I used 72 fps or higher multiples of 72 on a 72hz monitor then things would be smooth regardless of how high the fps was.

So the conclusion:

Use multiples of your monitor's refresh rate for maximum smoothness.. But keep in mind that this can potentially result in more noticeable tear lines.

Hey Tuna, are you able to do a timedemo on FS vs LA e1m2 4on4 (that comes bundled in nQuake)? that is the best demo to use.

Yeah there is a quite a big difference and very easy to tell.

To answer BloodDog(BigDick) - Look at an item and move your mouse left and right so your crosshair goes either side of an item that you are looking at. The higher the fps, the less blurry the item is. This also goes for enemies that you are aiming at. 616fps is probably the minimum you want to use, 770 and 1001 are also good but the optimal value i've tested is 1155. anything above that yields diminishing returns.

Oh and you can enable the vidlag hud element which shows the delay in how long a frame was rendered. the higher the fps, the lower the delay

Using the nQuake package is probably the best comparison for benchmarking, but be aware that timedemo will give lower average FPS than you get while playing as VWEP's are enabled during demo playback.

WQHD

24819 frames 36.6 seconds 678.1 fps


SVGA (-window)

24819 frames 19.2 seconds 1292.1 fps


This is vanilla ezQuake config. Couldn't run on nQuake due to missing correct libjpeg library and I didn't even try messing with configs. All Linux.

Note that the 3400G has 11 GPU CUs while the Athlon 3000 has only 3 I believe. That may make quite a difference. And of course ram speed may have an impact. Never tested whether it makes a significant difference for Quake. I run 3200 Mhz dual channel.

Can you try the timedemo again but set r_dynamic 0 and gl_detail 0 first? Maybe also try gl_max_size 32.

Sure can do.. i can use a config ttoo if you provide one. Also hope to upgrade to 4700G when its available and if it runs on this board..

My config comes bundled with nQuake or its on the front page of qw.nu to download. Can you load that config and do a timedemo of the e1m2 4on4 demo that comes with nquake? that would be so good. Thanks Tuna!
