With ez (gl-1754), it seems that flying grenades and rockets are kind of jerky on ktpro (using 1.67 + mvdsv 0.25).

Like if you firing gl at about 45 degrees and look to grenade model the movement is quite discrete.
But do the same on kteams 2.21 or ez in-built server and you will get silky smooth movement.

Tried internet servers - on ffa port grenades are smooth, on ktpro port of the same server they are jerky.

Considering it is perfectly fine on mq0.96, probably the reason is ez's independent physics (which is great feature by the way). Looks like with -noindphys grenades are flying fine, but I am not sure.

Can someone confirm this?

Yes, entities are jerky.

I always thought that mvdsvs sys_select_timeout problem, u may try set it to 10 and entities will be more smooth. But then I see u notice ffa mods, and now I know why on ffa servers its smooooth, it is because ffa servers do _not_ use serverinfo maxfps(at least most of ffa servers), so client use 72 maxfps instead(by default). Set serverinfo maxfps 70 on ktpro server and get same result, 70 even more smooth than 72 imo.

Seems something broken(or hardcoded to ~72fps) in interpolation code.

Here is my findings:

ez in-built: smooth
just plain mvdsv.exe: smooth
old 0.14beta mvdsv.exe: smooth
0.12 zqwsv.exe: smooth
mvdsv.exe +gamedir kteam: smooth
mvdsv.exe +gamedir ktpro: not smooth

I tried localinfo maxfps 70, serverinfo maxfps 70, localinfo current_fps 72, localinfo fps_phis 0 and it always not smooth in ktpro

I made an empty folder, put a latest qwprogs.dat from ktpro and run
mvdsv.exe +gamedir ktpro_stripped

map dm4
localinfo k_prewar 1

... not smooth

I alsto tried 1.53 ktpro with same result, that's the oldest version I have.

Looks like ktpro problem for me, except the one weird thing:
on the same ktpro servers with mqwcl 0.96 grenades are flying smooth.

I leave conclusions to you.

I recall mqwcl had a client-side rocket and grenade smoothing option. I don't have a copy installed but it could be cl_smooth_grenades or something?

povohat
Yes, it's cl_smooth_grenades. But I can't see the difference between 0 and 1, for mq it's smooth in both cases.

But you pointed me in the right direction - sv_mintic. I set it to 0.012 and get same smooth grenades on ktpro as on other servers (with ez client).

Damn. I always thought that 0.013 fits with 77 fps: 1/77 = 0.(012987)

Or it shouldn't?

beware the sv_mintic command. The lower the value, the more bandwith the server consumes. (confirm this? in netquake days was true). Ofc its beautiful
